(3) Synchronous/Asynchronous Alternate
Transmit Mode
Synchronous/asynchronous alternate transmit mode is selected
by setting the transmit enable bit in the serial I/O control register to
“1” after setting the synchronous serial I/O output pin selection bit
in the peripheral function expansion register to “1”. Set the syn-
chronous serial I/O output pin selection bit to “1” when the serial I/
O mode selection bit is set to “0”. In this mode, transmit cannot be
performed continuously. Write to the transmit buffer register after

changing the serial I/O mode selection bit. The SRDY output func-
tion cannot be used when the clock synchronous serial I/O is
selected. Also, when using the internal clock for the transfer clock
(the serial I/O synchronous clock selection bit is set to “0”), apply
“H” output to the P46 pin. The other operation is the same as clock
synchronous serial I/O mode and asynchronous serial I/O mode
(UART).
