1. Select receive mode.
2. Set acknowledgement data.
3. Start receiving. The first read is a dummy read.
4. Wait for 1 byte to be received.
5. Set acknowledgement data for the last receive.
6. Start the last receive.
7. Wait for 1 byte to be received.
8. Select transmit mode.
9. Read the last receive data (if ICDR is read
without selecting transmit mode, receive
operations will resume).
10. Generate a stop condition.
