EHACK bit in register SMB0ADM is cleared to 0
Firmware on the device must detect incoming slave addresses and ACK or
NACK the slave address and incoming data bytes.
EHACK bit in register SMB0ADM is set to 1
Automatic slave address recognition and ACK generation is enabled in hardware
Transmit mode always interrupts after the ACK/NAK
Indicates a successful transfer
•Receiver—writing the ACK bit defines the outgoing ACK value
•Transmitter—reading the ACK bit indicates the value received during the last ACK
cycle
•Receiver—the value currently specified by the ACK bit will be automatically sent on
the bus during the ACK cycle of an incoming data byte
•Transmitter—reading the ACK bit indicates the value received on the last ACK cycle
