Description
Divisor latch access.
Set by the user to enable access to the
COMxDIV0 and COMxDIV1 registers.
Cleared by the user to disable access to
COMxDIV0 and COMxDIV1 and enable access to
COMxRX and COMxTX.
Set break.
Set by the user to force SOUTx 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 1½ stop bits if the word
length is five bits or two stop bits if the word
length is six bits, seven bits, 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.

Description
Reserved.
Loop back.
Set by the user to enable loopback mode.
In loopback mode, SOUTx is forced high.
The modem signals are also directly con-
nected to the status inputs (RTS to CTS and
DTR to DSR).
Cleared by the user to be in normal mode.
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 1½ stop bits if
the word length is five bits or two stop bits
if the word length is six bits, seven bits, 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.
Request to send.
Set by the user to force the RTS output to 0.
Cleared by the user to force the RTS output
to 1.
Data terminal ready.
Set by the user to force the DTR output to
0.
Cleared by the user to force the DTR output
to 1.
