5.6 Serial Interface
Three channels of the serial interface are incorporated.
Serial interface UART0
Serial interface SIO3n (n = 0, 1) : 2 channels
: 1 channel
(1) Serial interface UART0
The serial interface UART0 has two modes, asynchronous serial interface (UART) mode and infrared data
transfer (IrDA) mode.
Asynchronous serial interface (UART) mode
This mode enables full-duplex operation wherein one byte of data is transmitted and received after the start
bit.
The on-chip dedicated UART baud rate generator enables communication using a wide range of selectable
baud rates. In addition, a baud rate can be also defined by dividing the clock input to the ASCK pin.
The dedicated UART baud rate generator can also be used to generate a MIDI-standard baud rate (31.25
kbps).
Infrared data transfer (IrDA) mode
This is a transfer mode (115.2 kbps) based on SIR (Serial Infrared) of the IrDA (Infrared Data Association)
standard. This mode can be used for office equipment applications such as personal computers.
