9.3.2

Start and stop conditions

As shown by Figure 38 a start condition is a HIGH to LOW transition of the SDA line while

SCL is HIGH. The stop condition is a LOW to HIGH transition of the SDA line while SCL is

HIGH.

9.3.3

Byte format

Every byte transferred to the SDA line must contain 8 bits. Each byte must be followed by an

acknowledge bit. The MSB is transferred first.

9.3.4

Acknowledge

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

pulse (see Figure 39). The receiver** 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 TDA75610DLVPD

–

slave (TDA75610DLVPD) when the µP reads a data byte from TDA75610DLVPD

** Receiver

–

slave (TDA75610DLVPD) when the µP writes an address to the TDA75610DLVPD

–

master (µP) when it reads a data byte from TDA75610DLVPD
