6. Clear the IRIC flag to 0.
7. To end transmission, clear the ACKE bit in ICCR to 0, to clear the acknowledge bit stored in
8. Clear the TRS bit to 0 for the next address reception, to set slave receive mode.
9. Dummy-read ICDR to release SCL on the slave side.

is high, the BBSY flag in ICCR is cleared to 0 and the STOP flag in ICSR is set to 1. At the
same time, the IRIC flag is set to 1. If the IRIC flag has been set, it is cleared to 0.
To restart slave transmit mode operation, make the initial settings once again.
