FEATURES
via I2C-bus
* Selection of non-volatile register_n as source to MUX_OUT pins * I2C-bus can override MUX_SELECT pin in selecting output
source
The PCA9561 typically resides between the CPU and Voltage Regulator Module (VRM) when used for CPU VID (Voltage IDentification code) configuration. It is used to bypass the CPU-defined VID values and provide a different set of VID values to the VRM, if an increase in the CPU voltage is desired. An increase in CPU voltage combined with an increase in CPU frequency leads to a performance boost of up to 7.5%. Lower CPU voltage reduces power consumption. The main advantage of the PCA9561 over older devices, such as the PCA9559 or PCA9560, is that it contains four internal non-volatile EEPROM registers instead of just one or two, allowing five independent settings which allows a more accurate CPU voltage tuning depending on specific applications. The PCA9561 has 2 address pins, allowing up to 4 devices to be placed on the same I2C-bus or SMBus.

DESCRIPTION
The PCA9561 is a 20-pin CMOS device consisting of four 6-bit non-volatile EEPROM registers, 6 hardware pin inputs and a 6-bit multiplexed output. It is used for DIP switch-free or jumper-less system configuration and supports Mobile and Desktop VID Configuration, where 5 preset values (4 sets of internal non-volatile registers and 1 set of external hardware pins) set processor voltage for operation in various performance or battery conservation sleep modes. The PCA9561 is also useful in server and telecom/networking applications when used to replace DIP switches or jumpers, since the settings can be easily changed via I2C/SMBus without having to power down the equipment to open the cabinet. The non-volatile memory retains the most current setting selected before the power is turned off.

DEVICE ADDRESS
Following a START condition the bus master must output the address of the slave it is accessing. The address of the PCA9561 is shown in Figure 1. To conserve power, no internal pull-up resistors are incorporated on the hardware selectable address pins and they must be pulled HIGH or LOW. The last bit of the slave address byte defines the operation to be performed. When set to logic 1 a read is selected while a logic 0 selects a write operation.
MSB 1 0 0 1 1 A1 A0 LSB R/W
CONTROL REGISTER
Following the successful acknowledgement of the slave address, the bus master will send a byte to the PCA9561, which will be stored in the control register. This register can be written and read via the I2C-bus.

REGISTER DESCRIPTION
If the command byte is an EEPROM address, the next byte sent will be programmed into that EEPROM address on the following STOP condition, if the WP is logic 0. If more than one byte is sent sequentially, the second byte will be written in the other-volatile register, on the following STOP condition. Up to four bytes can be sent sequentially. If any more data bytes are sent after the second byte, they will not be acknowledged and no bytes will be written to the non-volatile registers. After a byte is read from or written to the EEPROM, the part automatically points to the next non-volatile register. If the command code was FFH, the MUX_IN values are sent with the three MSBs padded with zeroes as shown below. If the command codes was 00H, then the non-volatile register 1 is sent, and if the command code was 01H, then the non-volatile register 1 is sent.

If the command byte is a MUX command byte, any additional data bytes sent after the MUX command code will not be acknowledged. If the read/write bit in the address is a logic 1, then a read operation follows and the data sent out depends on the previously stored command code. The MUX_SELECT_1 pin can function as the over-ride pin as on the PCA9559 if the non-volatile register 1 is left at all 0s. The NON_MUXED_OUT pin is a latched output. It is latched when MUX_SELECT_0 = 1. It is transparent when the MUX_SELECT_0 = 0. The data sent out on the NON_MUXED_OUT output is the 6th most significant bit of the non-volatile register. Whether this comes from the non-volatile register 0 or non-volatile register 1 depends on the command code or the external mux-select pins. After a valid I2C write operation to the EEPROM, the part cannot be addressed via the I2C for 3.6 ms. If the part is addressed prior to this time, the part will not acknowledge its address. NOTE: 1. To ensure data integrity, the non-volatile register must be internally write protected when VDD to the I2C-bus is powered down or VDD to the component is dropped below normal operating levels.

EXTERNAL CONTROL SIGNALS
The Write Protect (WP) input is used to control the ability to write the content of the non-volatile registers. If the WP signal is logic 0, the I2C-bus will be able to write the contents of the non-volatile registers. If the WP signal is logic 1, data will not be allowed to be written into the non-volatile registers. In this case, the slave address and the command code will be acknowledged but the following data bytes will not be acknowledged and the EEPROM is not updated. The factory default for the contents of the non-volatile register are all logic 0. These stored values can be read or written using the I2C-bus (described in the next section). The WP, MUX_IN*, and MUX_SELECT signals have internal pull-up resistors. See the DC and AC Characteristics for hysteresis and signal spike suppression figures.
Function Table1
WP 0 1 X X MUX_SELECT X X 0 1 COMMANDS Write to the non-volatile registers through I2C-bus allowed Write to the non-volatile registers through I2C-bus not allowed MUX_OUT from EEPROM byte 0-3 (EEPROM selected through I2C - see Table 2) MUX_OUT from MUX_IN inputs
NOTE: 1. This table is valid when not overridden by I2C control register.
POWER-ON RESET (POR)
When power is applied to VDD, an internal power-on reset holds the PCA9561 in a reset state until VDD has reached VPOR. At that point, the reset condition is released and the PCA9561 volatile registers and state machine will initialize to their default states. The MUX_OUT pin values depend on the MUX_SELECT logic level: - if MUX_SELECT = 0, the MUX_OUT pin output values will equal the previously stored EEPROM byte 0 values regardless of the last non-volative EEPROM byte selected by the command byte prior to power down. - if MUX_SELECT = 1, the MUX_OUT output values will equal the MUX_IN pin input values as shown in the Function Table.

CHARACTERISTICS OF THE I2C-BUS
The I2C-bus is for 2-way, 2-line communication between different ICs or modules. The two lines are a serial data line (SDA) and a serial clock line (SCL). Both lines must be connected to a positive supply via a pull-up resistor when connected to the output stages of a device. Data transfer may be initiated only when the bus is not busy.
Bit transfer
One data bit is transferred during each clock pulse. The data on the SDA line must remain stable during the HIGH period of the clock pulse as changes in the data line at this time will be interpreted as control signals (see Figure 3).
SDA
SCL data line stable; data valid change of data allowed SW00363
Figure 3. Bit transfer
Start and stop conditions
Both data and clock lines remain HIGH when the bus is not busy. A HIGH-to-LOW transition of the data line, while the clock is HIGH is defined as the start condition (S). A LOW-to-HIGH transition of the data line while the clock is HIGH is defined as the stop condition (P) (see Figure 4).
System configuration
A device generating a message is a `transmitter', a device receiving is the `receiver'. The device initiates a transfer is the `master' and the devices which are controlled by the master are the `slaves' (see Figure 5).

Acknowledge
The number of data bytes transferred between the start and the stop conditions from transmitter to receiver is not limited. Each byte of eight bits is followed by one acknowledge bit. The acknowledge bit is a HIGH level put on the bus by the transmitter whereas the master generates an extra acknowledge related clock pulse. A slave receiver which is addressed must generate an acknowledge after the reception of each byte. Also a master must generate an acknowledge after the reception of each byte that has been clocked out of the slave transmitter. The device that acknowledges has to pull down the SDA line during the acknowledge clock pulse, so that the SDA line is stable LOW during the HIGH period of the acknowledge related clock pulse, set-up and hold times must be taken into account. A receiver must signal an end of data to the transmitter by not generating an acknowledge on the last byte that has been clocked out of the slave. In this event, the transmitter must leave the data line HIGH to enable the master to generate a stop condition.
