9. Clear the IRIC flag in ICCR to cancel wait operation. The master device outputs the 9th clock
10. Set the ACKB bit in ICSR to 1 so as to return “No acknowledge” data. Also set the TRS bit in
11. Clear IRIC flag to 0 to release from the Wait State.
12. When one frame of data has been received, the IRIC flag is set to 1 at the rise of the 9th
13. Clear the WAIT bit to 0 to switch from wait mode to no wait mode. Read ICDR and the IRIC
14. Clear the BBSY bit and SCP bit to 0. This changes SDA from low to high when SCL is high,
