(1) Clock asynchronous (7 bits): Received D7 is transferred to b8 in the U2RB register.
(2) Clock asynchronous (8 bits): Received D8 is transferred to b8 in the U2RB register.
(3) Clock asynchronous (7 bits): b8 in the U2TB register is transferred externally as transfer data D7.
(4) Clock asynchronous (8 bits): b8 in the U2TB register is transferred externally as transfer data D8.
(5) PAR is disabled.
