7.5.1 Asynchronous serial interface/3-wire serial I/O (UART/IOE)
Two serial interface channels from which asynchronous serial interface mode and three-wire serial I/O mode
can be selected are provided.
(1) Asynchronous serial interface mode
In this mode, 1-byte data following a start bit is transferred or received.
The internal baud rate generator allows communication in a wide range of baud rates.
The clock input to the ASCK pin can also be divided to define a baud rate.
The baud rate generator can also set a baud rate conforming to the MIDI standard (31.25 kbps).
