functions (cont?d) symbol pin number type reset state function SAL-XC886CLM functional description data sheet 16 v1.0, 2010-05 3 functional description chapter 3 provides an overview of the sal -xc886 functional description. 3.1 processor architecture the sal-xc886 is based on a high-performance 8-bit centra l processing unit (cpu) that is compatible with th e standard 8051 processor. wh ile the standard 8051 processor is designed around a 12-clo ck machine cycle, the sal-xc8 86 cpu uses a 2-clock machine cycle. this allows fast access to rom or ram me mories without wait state. access to the flash memory, however, requ ires an additional wait state (one machine cycle). the instruction set co nsists of 45% one-byte, 41% two-byte and 14% three-byte instructions. the sal-xc886 cpu provides a range of debugging features, including basic stop/start, single-step execution, break point support and r ead/write access to the data memory, program memory and special function registers (sfrs). figure 5 shows the cpu functional blocks. figure 5 cpu block diagram register interface alu uart core sfrs 16-bit registers & memory interface opcode decoder state machine & power saving interrupt

five address spaces: ? 12 kbytes of boot rom program memory ? 256 bytes of intern al ram data memory ? 1.5 kbytes of xram memory (xram can be read/written as program memory or exter nal data memory) ? a 128-byte special function register area ? 24/32 kbytes of flash program memory figure 6 illustrates the memory address spaces of the 32-kbyte flash devices. for the 24-kbyte flash devices, the shaded banks are not available. figure 6 memory map of sal-xc886 flash device 0000 h 2000 h 4000 h 6000 h f000 h c000 h f600 h ffff h 7000 h 8000 h p-flash banks 2 and 3 2 x 4 kbytes boot rom 12

sal-xc886 memory prot ection strategy includes: ? read-out protection: the user is able to protect the contents in the flash memory from being read ? flash protection is enabled by progr amming a valid password (8-bit non-zero value) via bsl mode 6. ? flash program and erase protection. 3.2.1.1 flash memory protection as long as a valid password is available, all external access to th e device, including the flash, will be blocked. for additional security, the flash hardware protection can be enabled to implement a second layer of read-out protection, as we ll as to enable progra m and erase protection. flash hardware protection is available only for flash devices and comes in two modes: ? mode 0: only the p-flash is prot ected; the d-flas h is unprotected ? mode 1: both the p-flash and d-flash are protected the selection of each prot ection mode and the restrictio ns imposed are summarized in table 3 . table 3 flash protection modes flash protection without hardware protection with hardware protection hardware protection mode -01 activation program a valid password via bsl mode 6 selection bit 4 of password = 0 b it 4 of password = 1 msb of password = 0 bit 4 of

used for disabling flash protection. here, the programmed pa ssword must be provided by the user. a password match triggers an automatic er ase of the protected p-flash and d-flash contents, including the prog rammed password. the flash protection is then disabled upon the next reset. although no protection schem e can be considered infall ible, the sal-xc886 memory protection strategy provides a very high level of prot ection for a general purpose microcontroller. external access to d-flash not possible not possible not possible d-flash program possible possible not possible d-flash erase

memory space in the range 80 h to ff h . all registers, except the program co unter, reside in the sfr area. the sfrs include pointers and r egisters that provide an inte rface between t he cpu and the on-chip peripherals. as the 128-sfr range is less than th e total number of registers required, address extension mechanisms ar e required to increa se the number of addressable sfrs. t he address extension mechanisms include: ? mapping ?paging 3.2.2.1 address extension by mapping address extension is performed at the syst em level by mapping. the sfr area is extended into two portions: the standard (non-mapped) sf r area and the mapped sfr area. each portion supports the same address range 80 h to ff h , bringing the number of addressable sfrs to 256. t he extended address rang e is not directly controlled by the cpu instruction itself, but is derived from bi t rmap in the system control register syscon0 at address 8f h . to access sfrs in the mapped area, bit rmap in sfr syscon0 must be set. alternatively, the sfrs in the standar d area can be accessed by clearing bit rmap. the sfr area can be selected as shown in figure 7 . as long as bit rmap is set, the mapped sfr area can be accessed. this bit is not cleared automatically by hardware. thus , before standard/ma pped registers are accessed, bit rmap must be cleared/set, resp ectively, by software.

SAL-XC886CLM functional description data sheet 23 v1.0, 2010-05 figure 8 address exte nsion by paging in order to access a register located in a pag e different from the actual o ne, the current page must be exited. this is done by reprog ramming the bit fi eld page in the page register. only then can th e desired access be performed. if an interrupt routine is initiated be tween the page register access and the module register access, and t he interrupt needs to access a regist er located in another page, the current page setting can be saved, the new one programm ed and the old page setting restored. this is possible with the storage fields stx (x = 0 - 3) for the save and restore action of the current page setting. by indicating which st orage bit field should be used in parallel with t he new page value, a sing le write operation can: ? save the contents of page in stx be fore overwriting with the new value (this is done in th e beginning of the interrupt routi ne to save the current page setting and program the new page number); or sfr0 sfr1 sfrx ?... page 0 sfr0 sfr1 sfry ?... page 1 ?... sfr0 sfr1 sfrz ?... page q mod_page.page sfr address (from cpu) sfr data (to/from cpu) rw module SAL-XC886CLM functional description data sheet 24 v1.0, 2010-05 ? overwrite the contents of page with the co ntents of stx, ignori ng the value written to the bit positions of page (this is done at the end of the interrupt ro utine to restore the previous page setting before the interrupt occurred) figure 9 storage el ements for paging with this mechanism, a certain number of interrupt routines (or other routines) can perform page changes without reading and stor ing the previously used page information. the use of only write oper ations makes the system simp ler and faster. consequently, this mechanism significantly improves the performance of short interrupt routines. the sal-xc886 supports lo cal address extension for: ? parallel ports ? analog-to-digital converter (adc) ? capture/compare unit 6 (ccu6) ? system control registers page st0 st1 st2 st3 value update from cpu stnr SAL-XC886CLM functional description data sheet 25 v1.0, 2010-05 the page register has th e following definition: mod_page page register for modu le mod reset value: 00 h 76543210 op stnr 0 page wwrrw field bits type description page [2:0] rw page bits when written, the value indicates the new page. when read, the value indica tes the currently active page. stnr [5:4] w storage number this number indicates whic h storage bit field is the target of the operation defined by bit field op. if op = 10 b , the contents of page are saved in stx before being overwritten with the new value. if op = 11 b , the contents of page are overwritten by the contents of stx. the value written to the bit positions of page is ignored. 00 st0 is selected. 01 st1 is selected. 10 st2 is selected. 11 st3 is selected. SAL-XC886CLM functional description data sheet 26 v1.0, 2010-05 3.2.3 bit protection scheme the bit protection scheme prevents direct software wr iting of selected bi ts (i.e., protected bits) using the passwd re gister. when the bi t field mode is 11 b , writing 10011 b to the bit field pass opens access to writing of all protect ed bits, and writing 10101 b to the bit field pass closes access to writing of all prot ected bits. in both case s, the value of the bit field mode is not changed even if passwd regi ster is written with 98 h or a8 h . it can only be changed wh en bit field pass is written with 11000 b , for example, writing d0 h to passwd register disables th e bit protec tion scheme. note that access is opened fo r maximum 32 cclks if the ?clo se access? password is not written. if ?open access? password is wr itten again before the end of 32 cclk cycles, there will be a recount of 32 cclk cycles. the protecte d bits include the n- and k- divider bits, ndiv and kdiv; the watchdog timer enable bit, wdten; and the power- down and slow-down en able bits, pd and sd. op [7:6] w operation 0x manual page mode. th e value of stnr is ignored and page is directly written. 10 new page programming with automatic page saving. the value written to the bit positions of page is stored. in pa rallel, the previous contents of page are save d in the storage bit field stx indicated by stnr. 11 automatic restore page action. the value written to the bit positions page is ignored and instead, page is overwritten by the contents of the storage bit field stx indicated by stnr. 0 3r reserved returns 0 if re ad; should be written with 0. field bits type description SAL-XC886CLM functional description data sheet 27 v1.0, 2010-05 3.2.3.1 password register passwd password register reset value: 07 h 76543210 pass protect _s mode wh rh rw field bits type description mode [1:0] rw bit protection scheme control bits 00 scheme disabled - di rect access to the protected bits is allowed. 11 scheme enabled - the bi t field pass has to be written with the passwor ds to open and close the access to prot ected bits.

embedded user-programm able non-volatile memory, allowing fast and reliable storage of user code and data. it is operated from a single 2.5 v supply from the embedded voltage regu lator (evr) and does not require additional programming or erasing volta ge. the sectorization of t he flash memory allows each sector to be er ased independently. features ? in-system programming (isp) via uart ?

f cclk = 20 mhz 7.5 %) is the maximum frequency range for flash read access. 3) values shown here are typical values. f sys = 80 mhz 7.5% is the only frequency range for flash programming and erasing. f sysmin is used for obtaining the worst case timing. SAL-XC886CLM functional description data sheet 50 v1.0, 2010-05 table 18 shows the flash data ret ention and endurance targets. 3.3.1 flash bank sectorization the sal-xc886 product family offers flash devices with either 24 kbytes or 32 kbytes of embedded flash me mory. each flash device consis ts of program flash (p-flash) and data flash (d-flash ) bank(s) with different sectorization shown in figure 10 . both types can be used for code and data storage. the label ?data? neither implies that the d-flash is mapped to the data memory regi on, nor that it can only be used for data storage. it is used to di stinguish the different fl ash bank sectorizations. the 32-kbyte flash device cons ists of 6 p-flash and 2 d- flash banks, while the 24- kbyte flash device consists of also of 6 p-flash banks but with the upper 2 banks only 2 kbytes each, and only 1 d-flash bank. the p-flash banks are always grouped in pairs. as such, the p-flash banks are also sometimes referred to as p-flash bank pair. each sect or in a p-flash bank is grouped with the corresponding sector from the other bank within a bank pair to form a p-flash bank pair sector. table 18 flash data retention and en durance (operating conditions apply) retention endurance 1) 1) one cycle refers to the programming of all wordlines in a sector and erasing of sector. the flash endurance data specified in table 18 is valid only if the following conditions are fulfilled: - the maximum number of erase cycles per flash sector must not exceed 100,000 cycles. - the maximum number of erase cycles per flash bank must not exceed 300,000 cycles. - the maximum number of program cycles per flash bank must not exceed 2,500,000 cycles. size remarks t a = -40 to 125 c t a = 125 to 150 c program flash 20 years 1,000 cycles up to 32 kbytes 2) 2) if no flash is used for data, the program flash size can be up to the maximum flash size available in the device variant. having more data flash will mean less flash is available for program flash. for 32-kbyte variant 20 years 1,000 c ycles up to 24 kbytes 2) for 24-kbyte variant data flash 20 years 1,000 cycles 3) 3) for t a = 125 to 150 c, refers to programming of second 8 bytes (bytes 8 to 15) per wl. 4 kbytes 1 kbyte 5 years 10,000 cycles 3) 1 kbyte 256 bytes 2 years 70,000 cycles 3) 512 bytes 128 bytes 2 years 100,000 cycles 3) 128 bytes 32 bytes SAL-XC886CLM functional description data sheet 51 v1.0, 2010-05 figure 10 flash bank sectorization the internal structure of each flash bank represents a sect or architecture for flexible erase capability. the minimum erase width is always a comple te sector, and sectors can be erased separately or in parallel. contrary to st andard eproms, erased flash memory cells contain 0s. the d-flash bank is divided into more physical sectors fo r extended erasing and reprogramming capability; even numbers for each sector size are provided to allow greater flexibility and the abilit y to adapt to a wide range of application requirements. 3.3.2 parallel read access of p-flash to enhance system performance, the p-flash ba nks are configured for parallel read to allow two bytes of linear c ode to be read in 4 x cclk cycles, compared to 6 x cclk cycles if serial read is perfo rmed. this is achieved by readi ng two bytes in parallel from a p-flash bank pair within the 3 x cclk cycles access time a nd storing them in a cache. subsequent read from the cache by the cpu does not require a wa it state and can be completed within 1 x cclk cycle. the result is the average instruction fetch time from the p-flash banks is reduced and thus, the mips (m ega instruction pe r second) of the system is increased. however, if the parallel read feature is not desir ed due to certain timing constraints, it can be disabled by calling the pa rallel read disable subroutine. sector 9: 128-byte sector 5: 256-byte sector 3: 512-byte sector 1: 1-kbyte sector 0: 1-kbyte sector 7: 128-byte sector 8: 128-byte sector 6: 128-byte sector 4: 256-byte sector 2: 512-byte sector 0: 3.75-kbyte p-flash d-flash sector 2: 128-byte sector 1: 128-byte SAL-XC886CLM functional description data sheet 52 v1.0, 2010-05 3.3.3 flash programming width for the p-flash banks, a programmed wordlin e (wl) must be erased before it can be reprogrammed as the flash cells can only withstand one gate dist urb. this means that the entire sector cont aining the wl must be erased sinc e it is impossible to erase a single wl. for the d-flash bank, the sa me wl can be progra mmed twice before er asing is required as the flash cells are able to withstand two gat e disturbs. this means if the number of data bytes that needs to be written is sm aller than the 32-byt e minimum programming width, the user can opt to program this nu mber of data bytes (x ; where x can be any integer from 1 to 31) first a nd program the remain ing bytes (32 - x) la ter. hence, it is possible to program the same wl, for example, with 16 bytes of data two times (see figure 11 ) figure 11 d-flash programming note: when programming a d-fl ash wl the second time, the previously programmed flash memory cells (whether 0s or 1s) should be reprogrammed with 0s to retain its original contents and to prevent ?over-programming?. 0000 ?.. 0000 h 0000 ?.. 0000 h 32 bytes (1 wl) 1111 ?.. 1111 h 0000 ?.. 0000 h 16 bytes 16 bytes 0000 ?.. 0000 h 1111 ?.. 1111 h flash memory cells 32-byte write buffers 1111 ?.. 0000 h 1111 ?.. 1111 h 0000 ?.. 0000 h 1111 ?.. 0000 h program 1 program 2 note: a flash memory cell can be programmed from 0 to 1, but not from 1 to 0. SAL-XC886CLM functional description data sheet 53 v1.0, 2010-05 3.4 interrupt system the xc800 core supports one non-maskable interrupt (nmi ) and 14 maskable interrupt requests. in addition to the standard interr upt functions supporte d by the core, e.g., configurable interrupt priori ty and interrupt masking, t he sal-xc886 interrupt system provides extended interrupt su pport capabilitie s

(gpio) or to perform alte rnate input/output functions for the on-chip peripherals. when configured as an output, the op en drain mode can be selected. port p2 is an inpu t-only port, providing gener al purpose i nput functions, alternate input fu nctions for the on-chip peripherals, and also analog inputs for the analog-to-digital converter (adc). bidirectional port features ? configurable pin

with embedded voltage regulator the sal-xc886 microcontrol ler requires two different levels of power supply: ? 5.0 v for the embedded voltag e regulator (evr) and ports ? 2.5 v for the core, memory, on-ch ip oscillator, and peripherals figure 20 shows the sal-xc886 power supply system. a power suppl y of 5.0 v must be provided from the external power supply pin. the 2.5 v power supply for the logic is generated by the evr. the evr helps to reduce the pow er consumption of the whole chip and the complexity of the applicatio n board design. the evr consists of a main voltage regula tor and a low power voltage regulator. in active mode, both voltage regulators are enabled. in power-down mode, the main voltage regulator is switched off, while the low power voltage re gulator continues to function and provide power supply to th e system with low power consumption. figure 20 sal-xc886 power supply system evr features ? input voltage ( v ddp ): 5.0 v ? output voltage ( v ddc ): 2.5 v

hardware rese t, watchdog timer reset, power-down wake-up re set, and brownout reset. when the sal-xc886 is first powered up , the status of certain pins (see table 22 ) must be defined to ensure pr oper start operation of the device . at the end of a reset sequence, the sampled values are latched to select the desired b oot option, which cannot be modified until the next power-on reset or hardware reset. th is guarantees stable conditions during the norma l operation of the device. in order to power up the system pr operly, the external reset pin reset must be asserted until v ddc reaches 0.9* v ddc . the delay of external reset ca n be realized by an external capacitor at reset pin. this capacitor value must be selected so that v reset reaches 0.4 v, but not before v ddc reaches 0.9* v ddc. a typical application example is shown in figure 21 . the v ddp capacitor value is 100 nf while the v ddc capacitor value is 220 nf. t he capacitor connected to reset pin is 100 nf. typically, the time taken for v ddc to reach 0.9* v ddc is less than 50 s once v ddp reaches 2.3v. hence, based on the condition that 10% to 90% v ddp (slew rate) is less than 500 s, the reset pin should be held low for 500 s typically. see figure 22 . figure 21 reset circuitry v ssp v ddp v ddc v ssc 5v reset evr vr v in 100nf 220nf typ. 100nf xc886 30k SAL-XC886CLM functional description data

when the chip is in po wer-down mode. a reset input pin reset is provided for th e hardware reset. the watchdog timer (wdt) module is also capable of resett ing the device if it detects a malfunction in the system. another type of reset that needs to be detected is a re set while the device is in power-down mode (wake-up reset). while the contents of the stat ic ram are undefined after a power-on reset, they are well defin ed after a wake-up reset from power-down mode. v ddp reset wit h capacitor 2.3v v ddc < 0.4v 0.9* v ddc 0v 5v 5v 2.5v voltage voltage time time typ. < 50 s SAL-XC886CLM

signifies that the particular fu nction is reset to its default state. 3.7.2 booting scheme when the sal-xc886 is re set, it must identify the type of configurati on with which to start the different modes once the reset sequenc e is complete. thus, boot configuration information that is required for activation of special modes and condit ions needs to be applied by the external world through input pins. after power-on reset or hardware reset, the pins mbc, tms and p0 .0 collectively select t he different boot options. table 22 shows the available boot opt ions in the sal-xc886. table 21

boot options are valid only with t he default set of uart and jtag pins. 3.8 clock generation unit the clock generation unit (cgu ) allows great flexibility in the clock generation for the sal-xc886. the power consumptio n is indirectly proportional to the freque ncy, whereas the performance of the microc ontroller is directly propor tional to the frequency. during user program execution, th e frequency can be programmed for an optimal ratio between performance and power cons umption. therefore the power consumption can be adapted to the actual application state. features ? phase-locked loop (pll) for multiplyin g clock source by different factors ?pll base mode ? prescaler mode ?pll mode ? power-down mode support the cgu consists of an oscillator circuit and a pll. in the sal-xc886, the oscillator can be from either of these two sources: t he on-chip oscillator (1 0 mhz) or the external oscillator (4 mhz to 12 mhz). the term ?osc illator? is used to re fer to both on-chip oscillator and external osci llator, unless otherwise stated . after the reset, the on-chip oscillator will be used by default.the external oscillator can be se lected via software. in addition, the pll prov ides a fail-safe logic to perform oscillator run and loss-of-lock detection. this allows emer gency routines to be executed for system recovery or to perform system shut down. 1) bsl mode is automatically entered if no valid password is installed and data at memory address 0000h equals zero. 2) osc is bypassed in multican bsl mode 3) normal user mode with standard jtag (t ck,tdi,tdo) pins
