Section 18 IrDA
18.1 Overview
The SH7729R has an on-chip Infrared Data Association (IrDA) interface which is based on the
IrDA 1.0 system and can perform infrared communication. It also can be used as the SCIF by
making register settings.
18.1.1 Features
• Conforms to the IrDA 1.0 system
• Asynchronous serial communication
 Data length: 8 bits
 Stop bit length: 1 bit
 Parity bit: None
• On-chip 16-stage FIFO buffers for both transmit and receive operations
• On-chip baud rate generator with selectable bit rates
• Guard functions to protect the receiver during transmission
• Clock supply halted to reduce power consumption when not using the IrDA interface
