3.3 Byte Format
Every byte transferred on the SDA line must contain 8 bits. Each byte must be followed by an acknowledge bit.
The MSB is transferred first.
3.4 Acknowledge
The master (mP) puts a resistive HIGH level on the SDA line during the acknowledge clock pulse (see fig. 7).
The peripheral (audioprocessor) that acknowledges has to pull-down (LOW) the SDA line during this clock
pulse.
The audioprocessor which has been addressed has to generate an acknowledge after the reception of each
byte, otherwise the SDA line remains at the HIGH level during the ninth clock pulse time. In this case the master
transmitter can generate the STOP information in order to abort the transfer.
3.5 Transmission without Acknowledge
Avoiding to detect the acknowledge of the audioprocessor, the
P can use a simpler transmission: simply it
waits one clock without checking the slave acknowledging, and sends the new data.
This approach of course is less protected from misworking.
