[10] Clear the STOP flag.
[11] Issue the stop condition.
[12] Wait for the creation of stop condition.
[13] Read the last byte of receive data.
[14] Clear RCVD.
[15] Set slave receive mode.
Note: Do not activate an interrupt during the execution of steps [1] to [3].
Supplementary explanation: When one byte is received, steps [2] to [6] are
Clear TEND, select master receive mode, and then clear TDRE.*
Set acknowledge to the transmit device.*
Dummy-read ICDDR.*
Wait for 1 byte to be received
Check whether it is the (last receive - 1).
Read the receive data last.
Set acknowledge of the final byte. Disable continuous reception (RCVD = 1).
Read the (final byte - 1) of receive data.
Wait for the last byte to be receive.
skipped after step [1], before jumping to step [7].
The step [8] is dummy-read in ICDRR.
