Figure 31-31. Repeated Start + Reversal from Write to Read Mode

1. In this case, if TWI_THR has not been written at the end of the read command, the clock is automatically stretched before

2. TXCOMP is only set at the end of the transmission because after the repeated start, SADR is detected again.

Reversal after a Repeated Start

Reversal of Read to Write

Reversal of Write to Read

As soon as a START is detected

The master initiates the communication by a read command and finishes it by a write command.
