TDA7563PD

I2C bus

6.6

Acknowledge

The transmitter(*) puts a resistive HIGH level on the SDA line during the acknowledge clock

pulse (see Figure 29). 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 TDA7563PD

– slave (TDA7563PD) when the µP reads a data byte from TDA7563PD

(**) Receiver

– slave (TDA7563PD) when the µP writes an address to the TDA7563PD

– master (µP) when it reads a data byte from TDA7563PD
