For targeting interrupt and program run to address 0x0008, ACC, R3(STATUS), R5(Program page) and R4(6,7) will be automatically saved and R3(6,7) R register page will set to PAGE0, and reload after the instruction "RETI". 3. Before using Key tone function, please set Port 76 as output type. 4. In EM78R813, pin EGIN1 and EGIN2 are shared with pin TIP and RIN, but they are independent in EM78P813 and EM78813. 5. In EM78R813, user can turn on one of FSK, DTMF and CW power at the same time. In OTP and mask version, user can turn on both CID(one of FSK and DRMF) or CW power at the same time, but FSK and DTMF power can not turn on simultaneously. 6. Please do not switch MCU operation mode from normal mode to sleep mode directly. Before into sleep mode, please switch MCU to green mode. 7.For accessing data ROM,EM78P813 (OTP) can work at 10.74MHz, but please note that ROM type EM78813 only can work at 5.37MHz 8. While switching main clock (regardless of high freq to low freq or on the other hand), adding 6 instructions delay (NOP) is required.

How to set start address for expanding Data ROM?
EM78815 support maximum 2M Byte expanding data memory, but user must fix the start address of external program at 0x00000 and set start address of expanding Data ROM by user. By this way, MCU will get data from external memory if the data ROM is over 256K. The width of an instruction is 13 bit and the data bus for external memory is 8bit, so an instruction will captured two address size and the LSB address of start address at external ROM will be 0. Besides, EM78815 only support MAX 128K program, so the start address of Data ROM will smaller than 256K-2 andA20, A19 and A18 will be 0 also. User only has to according to write Data ROM address A17~A1 to IOCB PAGE2 bi7,RF PAGE3 and RF PAGE2.

External 128K x 13 PROGRAM ROM addresses to the relative programming instruction codes. The structure is depicted in Fig.8 "JMP" instruction allows the direct loading of the low 10 program counter bits. "CALL" instruction loads the low 10 bits of the PC, PC+1, and then push into the stack. "RET'' ("RETL k", "RETI") instruction loads the program counter with the contents at the top of stack. "MOV R2,A" allows the loading of an address from the A register to the PC, and the ninth and tenth bits are cleared to "0''. "ADD R2,A" allows a relative address be added to the current PC, and contents of the ninth and tenth bits are cleared to "0''. "TBL" allows a relative address be added to the current PC, and contents of the ninth and tenth bits don't change. The most significant bit (A10~A14) will be loaded with the content of bit PS0~PS3 in the status register (R5) upon the execution of a "JMP'', "CALL'', "ADD R2,A'', or "MOV R2,A'' instruction. If a interrupt trigger, PROGRAM ROM will jump to address 8 at page0. The CPU will store ACC,R3 status and R5 PAGE automatically, it will restore after instruction RETI.

Fig.7 shows how SPI to communicate with other device by SPI module. If SPI is a master controller, it sends clock through the SCK pin. An 8-bit data is transmitted and received at the same time. If SPI, however, is defined as a slave, its SCK pin could be programmed as an input pin. Data will continue to be shifted on a basis of both the clock rate and the selected edge.

Presents a logic high when a received tone-pair has been registered and the output latch updated; returns to logic low when the voltage on St/GT falls below V tst. 0/1 Data invalid/data valid Be sure open main clock before using DTMF receiver circuit . A logic"0,0" applied to R5 page3 b4 and b3 will shut down power of the device to minimize the power consumption in a standby mode. It stops functions of the filters.
In many situations not requiring independent selection of receive and pause, the simple steering circuit of is applicable. Component values are chosen according to the following formulae:
t REC = t DP + t GTP t ID = t DA + t GTA The value of t DP is a parameter of the device and t REC is the minimum signal duration to be recognized by the receiver. A value for C of 0.1 uF is recommended for most applications, leaving R to be selected by the designer. For example, a suitable value of R for a t REC of 30mS would be 300k. Different steering arrangements may be used to select independently the guard-times for tone-present (t GTP ) and tone-absent (t GTA ). This may be necessary to meet system specifications which place both accept and reject limits on both tone duration and inter digital pause. Guard-time adjustment also allows the designer to tailor system parameters such as talk off and noise immunity. Increasing t REC improves talk-off performance, since it reduces the probability that tones simulated by speech will maintain signal condition for long enough to be registered. On the other hand, a relatively short t REC with a long t DO would be appropriate for extremely noisy environments where fast acquisition time and immunity to drop-outs would be required.

Bit 1 (/CD) : FSK carrier detect indication 0/1 Carrier Valid/Carrier Invalid It's a read only signal. If FSK decoder detect the energy of mark or space signal. The Carrier signal will go to low level. Otherwise it will go to high.. Note!! Should be at normal mode. Bit 2 (FSKDATA) : FSK decoding data output It's a read only signal. If FSK decode the mark or space signal , it will output high level signal or low level signal at this register. It's a raw data type. That means the decoder just decode the signal and has no process on FSK signal. Note!! Should be at normal mode. User can use FSK data falling edge interrupt function to help data decoding. Example: MOV A,@01000000 IOW IOCF ;enable FSK interrupt function CLR RF ENI ;wait for FSK data's falling edge : 0 = Space data ( 2200Hz ) 1 = Mark data (1200Hz) FSK block power is controlled by R5 page3 bit3,4. When PCTRI1=0 and PCTRL0=1 , FSK power on. The relation between R5 bit3 to bit4 and RA bit1 to bit 2 are show in Fig.14. You have to power FSK decoder up first, then wait a setup time (Tsup) and check carrier signal (/CD). If the carrier is low, program can process the FSK data.

Fig.18 The relation between R5 bit3 to bit4 and RA bit1 to bit 2 The controller is a CMOS device designed to support the Caller Number Deliver feature which is offered by the Regional Bell Operating Companies. The FSK block comprises one path: the signal path. The signal path consist of an input differential buffer, a band pass filter, an FSK demodulator and a data valid with carrier detect circuit. In a typical application, user can use his own external ring detect output as a triggering input to IO port. User can use this signal to wake up whole chip by external ring detect signal. By setting "0,1" to R5 b4 and b3 (PCTRL1 & PCTRL0) of register RA to activate the block of FSK decoder. If b4 and b3 of register R5 is set to "0,1", the block of FSK decoder will be powered down. The input buffer accepts a differential AC coupled input signal through the TIP and RING input and feeds this signal to a band pass filter. Once the signal is filtered, the FSK demodulator decodes the information and sends it to a post filter. The output data is then made available at bit 2 (FSKDATA) of register RA. This data, as sent by the central office, includes the header information (alternate "1" and "0") and 150 ms of marking which precedes the date, time and calling number. If

no data is present, the bit 2 (DATA) of register RA is held on "1" state. This is accomplished by an carrier detect circuit which determines if the in-band energy is high enough. If the incoming signal is valid, bit 1 (/CD) of register RA will be "0" otherwise it will be held on "1". And thus the demodulated data is transferred to bit 2 (DATA) of register RA. If it is not, then the FSK demodulator is blocked. Bit 3 (ROMRI) : External Data ROM read data address auto_increase enable.

LCD1 LCD0 LCD operation 0 0 Disable 0 1 Blanking 1 0 Reserved 1 1 LCD enable Key strobe and Key check functions should be normal operating whenever LCD is enabled or disabled. When LCD operation disable: (1) Internal Voltage regulator will disable and VREF pin is into high impedance. (2) Charge pump circuit disable. (3) Internal non-Inverter OP Amp power off. The controller can drive LCD directly. LCD block is made up of LCD driver, display RAM, segment output pins, common output pins and LCD operating bias pins. Duty is determined by RD PAGE2 bit5. The number of segment , the number of common and frame frequency are determined by LCD mode register RE PAGE2 Bit 0~ Bit 1. When 16 LCD commons and 1/4 duty are used, LCD operating bias pins VC1, VC2, VC4 and VC5 need to be connected 0.1uF capacitors to the ground (VC3 is not necessary). When 24 and 32 LCD common is used, all LCD operating bias pins VC1 ~ VC5 need to be connected 0.1uF capacitors to the ground. LCD driver can be controlled as different driving ability (refer to RD PAGE2 register). The basic structure contains a timing control which uses the basic frequency 32.768kHz to generate the proper timing for different duty and display access. RE PAGE2 register is a command register for LCD driver and display. The LCD display (disable, enable, blanking) is controlled by RE PAGE0 Bit 2 ~ Bit 3 and the driving duty is decided by RE PAGE2 Bit 0 ~ Bit 1. LCD display data is stored in data RAM which address and data access controlled by registers R9, RA PAGE1 and RB PAGE1. User can regulate the contrast of LCD display by RD PAGE2 (BIAS4..BIAS0). Up to 32 levels contrast is convenient for better display. And the internal voltage follower can afford large driving source. Bit 4 (KEYSCAN) : Key scan function enable control bit 0/1 disable/enable If you enable key scan function LCD waveform will has a small pulse within a period like fig.23

Fig.32 The circuit of I/O port and I/O control register The I/O registers are bi-directional tri-state I/O ports. The I/O ports can be defined as "input" or "output" pins by the I/O control registers under program control. The I/O registers and I/O control registers are both readable and writable. The I/O interface circuit is shown in Fig.27
VII.5 RESET
The RESET can be caused by (1) Power on voltage detector reset (POVD) and power on reset (2) WDT timeout. (if enabled and in GREEN or NORMAL mode) (3) /RESET pin pull low At case (1), POVD is controlled by CODE OPTION. If you enable POVD, CPU will reset at 2V under. And CPU will consume more current about 3uA . And the power on reset is a circuit always enable. It will reset CPU at about 1.4V and consume about 0.5uA. Once the RESET occurs, the following functions are performed. * The oscillator is running, or will be started. * The Program Counter (R2) is set to all "0". * When power on, the upper 3 bits of R3 and the upper 2 bits of R4 are cleared. * The Watchdog timer and prescaler counter are cleared. * The Watchdog timer is disabled. * The CONT register is set to all "1" * The other register (bit7..bit0)

VII.6 wake-up
The controller provided sleep mode for power saving. SLEEP mode , RA(7)=0 + "SLEP" instruction . The controller will turn off all the CPU and crystal. Other circuit with power control like key tone control or PLL control (which has enable register), user has to turn it off by software. Wake-up from SLEEP mode : (1) WDT time out (2) external interrupt (3) /RESET pull low All these cases will reset controller , and run the program at address zero. The status just like the power on reset. Be sure to enable circuit at case (1) or (2).
VII.7 Interrupt
RE and RF is the interrupt status register which records the interrupt request in flag bits. IOCE and IOCF is the interrupt mask register. TCC timer, Counter1 and Counter2 are internal interrupt source. P70 ~ P77(INT0 ~ INT7) are external interrupt input which interrupt sources are come from the external. If the interrupts are happened by these interrupt sources, then RE or RF register will generate '1' flag to corresponding register if you enable IOCE or IOCF register. Global interrupt is enabled by ENI instruction and is disabled by DISI instruction. When one of the interrupts (when enabled) generated, will cause the next instruction to be fetched from address 008H. Once in the interrupt service routine the source of the interrupt can be determined by polling the flag bits in the RE and RF register. The interrupt flag bit must be cleared in software before leaving the interrupt service routine and enabling interrupts to avoid recursive interrupts.

VII.8 Instruction Set
Instruction set has the following features: (1) Every bit of any register can be set, cleared, or tested directly. (2) The I/O register can be regarded as general register. That is, the same instruction can operates on I/O register. The symbol "R" represents a register designator which specifies which one of the 64 registers (including operational registers and general purpose registers) is to be utilized by the instruction. Bits 6 and 7 in R4 determine the selected register bank. "b'' represents a bit field designator which selects the number of the bit, located in the register "R'', affected by the operation. "k'' represents an 8 or 10-bit constant or literal value.

Fig.33 Call Waiting Block Diagram Call Waiting service works by alerting a customer engaged in a telephone call to a new incoming call. This way the customer can still receive important calls while engaged in a current call. The CALL WAITING DECODER can detect CAS(Call-Waiting Alerting Signal 2130Hz plus 2750Hz) and generate a valid signal on the data pins. The call waiting decoder is designed to support the Caller Number Deliver feature, which is offered by regional Bell Operating Companies. In a typical application, after enabling CW circuit (by R5 page3 bit3 & bit4 ) this IC receives Tip and Ring signals from twisted pairs. The signals as inputs of pre-amplifier, and the amplifier sends input signal to a band pass filter. Once the signal is filtered, the Detection block decodes the information and sends it to RE page2 bit7 . The output data made available at RE CAS bit. The data is CAS signals. The CAS is normal high. When this IC detects 2130Hz and 2750Hz frequency, then CAS pin goes to low.
