Description
Divisor latch access.
Set by the user to enable access to COMDIV0 and COMDIV1 registers.
Cleared by the user to disable access to COMDIV0 and COMDIV1 and enable access to COMRX,
COMTX, and COMIEN0.
Set break.
Set by the user to force the transmit pin (SOUT) to 0.
Cleared to operate in normal mode.
Stick parity. Set by the user to force parity to defined values.
1 if EPS = 1 and PEN = 1.
0 if EPS = 0 and PEN = 1.
Even parity select bit.
Set for even parity.
Cleared for odd parity.
Parity enable bit.
Set by the user to transmit and check the parity bit.
Cleared by the user for no parity transmission or checking.
Stop bit.
Set by the 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.
Word length select.
00 = five bits.
01 = six bits.
10 = seven bits.
11 = eight bits.
