[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.
Notes: * Make sure that no interrupt will be generated during steps [1] to [3].
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.
Set acknowledge of the final byte. Disable continuous reception (RCVD = 1).
Read the (final byte - 1) of received data.
Wait for the last byte to be receive.
When the size of receive data is only one byte in reception,
The step [8] is dummy-read in ICDRR.
steps [2] to [6] are skipped after step [1], before jumping to step [7].
However, when the size of receive data is two bytes and more,
steps [2] to [6] are not skipped after step [1].
