UART REGISTER DEFINITION
The UART interface consists of 9 registers namely:
- COMTX: 8-bit transmit register
- COMRX: 8-bit receive register
- COMDIV0: divisor latch (low byte)
COMTX, COMRX and COMDIV0 share the same address
location. COMTX and COMTX can be accessed when bit 7 in
COMCON0 register is cleared. COMDIV0 can be accessed
when bit 7 of COMCON0 is set.
- COMDIV1: divisor latch (high byte)
- COMCON0: line control register
- COMSTA0: line status register
- COMIEN0: interrupt enable register
- COMIID0: interrupt identification register
- COMDIV2: 16-bit fractional baud divide register

Read Only
This 8-bit register is read from to receive data
transmitted via the UART.
COMDIV0
0xFFFF0700
0x00
Read/Write
This 8-bit register contains the least significant
byte of the divisor latch witch controls the baud
rate at which the UART operates.

0x00
Read/Write
This 8-bit register contains the most significant
byte of the divisor latch witch controls the baud
rate at which the UART operates.
