16.1 Functions of Serial Interface UART0
(1) Operation stop mode
(2) Asynchronous serial interface (UART) mode (fixed to LSB first)
(3) Infrared data transfer mode
Serial interface UART0 has the following three modes.
This mode is used when serial transfers are not performed to reduce power consumption.
For details, see 16.4.1 Operation stop mode.
This mode enables full-duplex operation wherein one byte of data after the start bit is transmitted and received.
The on-chip baud rate generator dedicated to UART enables communications using a wide range of selectable
baud rates. The communication range is between 1.2 kbps and 131 kbps (when operated at f
In addition, a baud rate (39 kbps max. (when operated at f
clock input to the ASCK0 pin.
The UART baud rate generator can also be used to generate a MIDI-standard baud rate (31.25 kbps).
For details, see 16.4.2 Asynchronous serial interface (UART) mode.
For details, see 16.4.3 Infrared data transfer mode.
