11.8.6.6 CIR Baud Rate Divisor Low Byte Register (BDLR)
The BDLR, an 8-bit
read/write
register, is used to program the CIR Baud Rate clock.
Address: Base address + 5h (when BR = 1)
Bit
7-0
R/W
Default
00h
Description
R/W
Baud Rate Divisor Low Byte (BDLR[7:0])
These bits are the low byte of the register used to divide the Baud Rate clock.
11.8.6.7 CIR Baud Rate Divisor High Byte Register (BDHR)
The BDHR, an 8-bit
read/write
register, is used to program the CIR Baud Rate clock.
Address: Base address + 6h (when BR = 1)
Bit
7-0
R/W
Default
00h
Description
R/W
Baud Rate Divisor High Byte (BDHR[7:0])
These bits are the high byte of the register used to divide the Baud Rate clock.
Baud rate divisor = 115200 / baud rate
Ex1: 2400bps
115200 /2400 = 48
48(d) = 0030 (h)
BDHR = 00(h), BDLR = 30(h)
Ex2: bit width = 0.565 ms
1770 bps
115200 / 1770 = 65(d) = 0041(h)
BDHR = 00(h), BDLR = 0041(h)
11.8.6.8 CIR Transmitter Status Register (TSR)
The TSR, an 8-bit
read only
register, provides the Transmitter FIFO status.
Address: Base address + 5h
Bit
R/W
Default
Description

Transmitter FIFO Byte Count (TXFBC[5:0])
Return the number of bytes left in the Transmitter FIFO.
