[1] Clear the AAS flag.
[2] Set acknowledge to the transmit device.
[3] Dummy-read ICDRR.
[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 last byte.
[8] Read the (last byte - 1) of receive data.
[9] Wait the last byte to be received.
[10] Read for the last byte of receive data.
Note: 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.
