sNotes on serial I/O
When setting transmit enable bit to “1”, the serial I/O transmit inter-
rupt request bit is automatically set to “1”. When not requiring the
interrupt occurrence synchronous with the transmision enabled, take
the following sequence.
Set the serial I/O transmit interrupt enable bit to “0” (disabled).
Set the transmit enable bit to “1”.
Set the serial I/O transmit interrupt request bit to “0” after 1 or more
instructions have been executed.
Set the serial I/O transmit interrupt enable bit to “1” (enabled).
