CHAPTER 12 SERIAL INTERFACE 20
12.4.2 Asynchronous serial interface (UART) mode
In this mode, the one-byte data following the start bit is transmitted/received, enabling full-duplex communication.
This device incorporates UART-dedicated baud rate generator that enables communications at the desired baud
rate. In addition, the baud rate can also be defined by dividing the clock input to the ASCK20 pin.
The UART-dedicated baud rate generator also can output the 31.25 kbps baud rate that complies with the MIDI
standard.
(1) Register setting
UART mode is set by serial operation mode register 20 (CSIM20), asynchronous serial interface mode
register 20 (ASIM20), asynchronous serial interface status register 20 (ASIS20), and baud rate generator
control register 20 (BRGC20).
