Acknowledge

The transmitter puts a resistive high level on the SDA line during the acknowledge clock

pulse (see Figure 18). The receiver the acknowledges has to pull-down (low) the SDA line

during the acknowledge clock pulse, so that the SDA line is stable low during this clock

pulse.

Transmitter:

●

master (µP) when it writes an address to the TDA7567PD

●

slave (TDA7567PD) when the µP reads a data byte from TDA7567PD

Receiver:

●

slave (TDA7567PD) when the µP writes an address to the TDA7567PD

●

master (µP) when it reads a data byte from TDA7567PD
