[4] Wait for 1 byte to be received
[5] Check whether it is the (last receive - 1).
[6] Read the receive data.
[7] Set acknowledge of the final byte.
[8] Read the (final byte - 1) of received data.
[9] Wait for the last byte to be receive.
[10] Clear the STOP flag.

When the size of receive data is only one byte in
reception, steps [2] to [6] are skipped after step [1],
before jumping to step [7].
The step [8] is dummy-read in ICDRR.
