6.3
W83877ATF/ATG includes two serial ports: UART A and UART B. The second serial port, UART B,
also has built-in 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).
6.3.1
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
used, 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. The structure of he Register Sets is shown below.
