HD6417320 RENESAS [Renesas Technology Corp], HD6417320 Datasheet - Page 701

• Manufacturer Part Number: HD6417320
• Description: Renesas 32-Bit RISC Microcomputer SuperHTM RISC engine Family / SH7700 Series
• Manufacturer: RENESAS [Renesas Technology Corp]

This LSI has an on-chip Infrared Data Association (IrDA) interface that is based on the IrDA 1.0
system and can perform infrared communication.
The IrDA is an optional module used for modulation and demodulation of signals for the SCIF_0
module, and it must always be used together with the SCIF_0 module.
19.1
• Conforms to the IrDA 1.0 system
• Asynchronous serial communication
• On-chip 64-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
Figure 19.1 shows a block diagram of the IrDA.
