12.1 Function of Serial Interfaces
222
Serial interfaces UART00 and UART01 have the following three modes.
• Operation stop mode
• Asynchronous serial interface (UART) mode
• Infrared data transfer mode (UART00 only)
(1) Operation stop mode
(2) Asynchronous serial interface (UART) mode
(3) Infrared data transfer mode (UART00 only)
This mode is used when serial transfer is not carried out, and is to reduce power consumption.
In this mode, one byte of data is transmitted/received following the start bit, and full-duplex operation is
possible.
A dedicated UART baud rate generator is incorporated, allowing communication over a wide range of baud
rates.
Programming baud rate generator control registers 0 and 1 (BRGC00 and BRGC01) allows a baud rate
selection of 600 bps to 115.2 kbps (@ f
operation) for UART00 and 300 bps to 38.4 kbps (@ f
f
This mode allows communication at a baud rate of 115.2 kbps (@ f

= 12 MHz operation) for UART01.
