Description
7
DLAB
Divisor latch access.
Set by user to enable access to COMDIV0 and COMDIV1.
Cleared by user to disable access to COMDIV0 and COMDIV1 and to enable access to COMRX, COMTX, and
COMIEN0.
6
BRK
Set break.
Set by user to force TxD to 0.
Cleared to operate in normal mode.
5
SP
Stick parity. Set by user to force parity to defined values.
1 if EPS = 1 and PEN = 1.
0 if EPS = 0 and PEN = 1.
4
EPS
Even parity select bit.
Set for even parity.
Cleared for odd parity.
3
PEN
Parity enable bit.
Set by user to transmit and check the parity bit.
Cleared by user for no parity transmission or checking.
2
Stop
Stop bit.
Set by user to transmit 1.5 stop bits if the word length is five bits, or two stop bits if the word length is six, seven, or
eight bits. The receiver checks the first stop bit only, regardless of the number of stop bits selected.
Cleared by the user to generate one stop bit in the transmitted data.
1 to 0 WLS
Word length select.
00 = five bits.
01 = six bits.
10 = seven bits.
11 = eight bits.
UART Control Register 1
Name: COMCON1
Address: 0xFFFF0710
Default Value: 0x00
Access: Read/write
Function: This 8-bit register controls the operation of the UART in conjunction with COMCON0.

Description
7 to 6 SMS
UART input mux.
00 = RxD driven by LIN input; required for LIN communications using the LIN pin.
01 = reserved.
10 = RxD driven by GP5; required for serial communications using the GPIO_5/IRQ1/RxD pin (RxD).
11 = reserved.
5
Reserved. Not used.
4
LOOPBACK Loopback. Set by user to enable loopback mode. In loopback mode, the TxD is forced high.
3 to 0
Reserved. Not used.
