** The percentage error for all baud rates, except where indicated otherwise, is 0.16%.
Note. Pre-Divisor is determined by CRF0 of UART A
8. INFRARED (IR) PORT
The Infrared (IR) function provides a point-to-point (or multi-point to multi-point) wireless
communication which can operate under various transmission protocols including IrDA 1.0 SIR, IrDA
1.1 MIR (1.152 Mbps), IrDA 1.1 FIR (4 Mbps), SHARP ASK-IR, and remote control (NEC, RC-5,
advanced RC-5, and RECS-80 protocol).
8.1
When bank select enable bit (ENBNKSEL, the bit 0 in CRF0 of logic device 6) is set, legacy IR will be
switched to Advanced IR, and eight Register Sets can then be accessible. These Register Sets
control enhanced IR, SIR, MIR, or FIR. Also a superior traditional SIR function can be used with
enhanced features such as 32-byte transmitter/receiver FIFOs, non-encoding IRQ identify status
register, and automatic flow control. The MIR/FIR and remote control registers are also defined in
these Register Sets. Structure of these Register Sets is asshown below.
