IRDA CONTROLLER
This chapter describes the functions and usage of IrDA Controller in S3C6400X RSIC microprocessor.
OVERVIEW
The Samsung IrDA Core is a wireless serial communication controller. The Samsung IrDA Core supports two
different types of IrDA speed (MIR, FIR). This core can transmit Ir(Infrared) pulses up to 4 Mbps speed. It
includes configurable FIFO feature to reduce the CPU burden. This makes it easy to adjust the internal FIFO
sizes.
You can program the core by accessing 16 internal registers. When receiving the Ir pulses, this core detects
three kinds of line errors such as CRC-error, PHY-error and payload length error.
