4.3 IR Port
In the W83877AF includes two serial ports, that is UART A and UART B. The second serial port,
UART B, also has built in the Infrared (IR) functions which include IrDA 1.0 SIR, IrDA 1.1 MIR
(1.152M bps), IrDA FIR (4M bps), SHARP ASK-IR, and remote control (that support NEC, RC-5,
advanced RC-5, and RECS-80 protocol).
4.3.1 Advanced UART B Register Description
When bank select enable bit (ENBNKSEL, in CR2C.bit3) is set, UART B will be switched to Advanced
UART B, and eight Register Sets can be accessed. These Register Sets control enhanced UART B,
IR function switching such as SIR, MIR, or FIR. Also a superior traditional UART B function can be
use such as 32-byte transmitter/receiver FIFO, 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 he Register Sets is shown as follows.
