Description
Divisor Latch Access.
Set Break.
Stick Parity. Set by user to force parity to defined values.
Even Parity Select Bit.
Parity Enable Bit.
Stop Bit.
Word Length Select.
Set by user to enable access to COMDIV0 and COMDIV1 registers.
Cleared by user to disable access to COMDIV0 and COMDIV1 and enable access to COMRX,
COMTX, and COMIEN0.
Set by user to force TxD to 0.
Cleared to operate in normal mode.
1 if EPS = 1 and PEN = 1.
0 if EPS = 0 and PEN = 1.
Set for even parity.
Cleared for odd parity.
Set by user to transmit and check the parity bit.
Cleared by user for no parity transmission or checking.
Set by the user to transmit 1.5 stop bits if the word length is 5 bits, or 2 stop bits if the word
length is 6, 7, or 8 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.
00 = 5 bits.
01 = 6 bits.
10 = 7 bits.
11 = 8 bits.
