11. Read the ACKB bit in ICSR.
12. Clear the IRIC flag to 0.
Note:
Data should not be
written to ICDR.
Confirm that the slave device returns acknowledgement (ACKB bit is 0). When there is still
data to be transmitted, go to step 9 to continue the next transmission. When the slave device
does not return acknowledgement (ACKB bit is set to 1), follow step 12 to end transmission.
Write 0 to the ACKE bit in ICCR, to clear the received ACKB bit to 0.
Write 0 to BBSY and SCP in ICCR. This changes SDA from low to high when SCL is high,
and generates the stop condition.
