I2C bus

TDA7563B

7.2.4

Acknowledge

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

pulse (see Figure 31). The receiver**, in order to acknowledge, 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 (P) when it writes an address to the TDA7563B

– slave (TDA7563B) when the P reads a data byte from TDA7563B

** Receiver

– slave (TDA7563B) when the P writes an address to the TDA7563B

– master (µP) when it reads a data byte from TDA7563B
