output a transfer end (force stop). When the last bit of a byte is transmitted/received, the I
module latches the FSB value and enters the stop state. Therefore, to stop the transfer after a
specified byte data is transferred, the FSB bit must be set before the last byte is transferred. If
the last byte is not correct, the protocol layer notifies the slave device that re-transmission is
needed.
