6.4.3.6.2 IrDA Features
UART3 supports the following IrDA key features:
- Support of IrDA 1.4 slow infrared (SIR), medium infrared (MIR), and fast infrared (FIR) communications:
- Frame formatting: Addition of variable beginning-of-frame (xBOF) characters and end-of-frame (EOF) characters
- Uplink/downlink cyclic redundancy check (CRC) generation/detection
- Asynchronous transparency (automatic insertion of break character)
- Eight-entry status FIFO (with selectable trigger levels) to monitor frame length and frame errors
- Framing error, CRC error, illegal symbol (FIR), and abort pattern (SIR, MIR) detection
