UART REGISTER DEFINITION
The UART interface consists of the following nine registers:
•
•
•
•
•
•
•
•
•
COMTX, COMRX, and COMDIV0 share the same address
location. COMTX and COMRX can be accessed when Bit 7 in
the COMCON0 register is cleared, and COMDIV0 can be
accessed when Bit 7 of COMCON0 is set.

COMDIV0
0x00
Read/write
This 8-bit register contains the LSB of the
divisor latch that controls the baud rate at
which the UART operates.
COMDIV1
0x00
Read/write
This 8-bit register contains the MSB of the
divisor latch that controls the baud rate at
which the UART operates.
COMCON0
0x00
Read/write
This 8-bit register controls the operation of the
UART in conjunction with COMCON1.
