GENERAL CALL WAKE-UP
If the second byte is “00001001” (09h), the device
forces the volatile power-down bits to ‘00’. The
nonvolatile (EEPROM) power-down bit values are not
affected by this command.
This command allows multiple MCP47X6 devices to
wake-up synchronously.
FIGURE 6-8:
General Call Wake-Up Command.
Note:
This command does not adhere to the I2C
specification where if the LSb of the 2nd
byte is a ‘1’, it is a ‘Hardware General Call’
(see the NXP I2C Specification).
General Call Address
Note 1: At the falling edge of the SCL, at the end of this ACK pulse, the volatile PD1:PD0 bits are forced to ‘00’.
Note 1
2: The 2nd byte can be repeated after the 2nd by continued clocking before issuing Stop bit.
General Call Wake-Up
3: ACK bit generated by MCP47X6.
