Preliminary Technical Data
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)
- COMCON0: line control register
- COMSTA0: line status register
- COMIEN0: interrupt enable register
- COMIID0: interrupt identification register
- COMDIV2: 16-bit fractional baud divide register
UART TX Register:
Name :
Address :
Default Value :
Access :
Function :
data via the UART.
UART RX Register:
Name :
Address :
Default Value :
Access :
Function :
data transmitted via the UART.
COMDIV1: divisor latch (high 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.
