Stick Parity bit.
Set Bit 5=1, Bit 4=1, & Bit 3=1, the Parity bit is transmitted and checked as logic 0.
Set Bit 5=1, Bit 4=0, & Bit 3=1, the Parity bit is transmitted and checked as logic 1.
Set Bit 5=0, Stick Parity is disabled.
Even Parity Select bit.
Set Bit 4=0 & Bit 3=1, an odd number of logic 1s is transmitted or checked in the data
Set Bit 4=1 & Bit 3=1, an even number of logic 1s is transmitted or checked.
Parity Enable bit.
Stop bit.
This bit specifies the number of Stop bits transmitted and received in each serial
Set 0: One Stop bit is generated in the transmitted data.
Set 1: One and a half stop bits are generated for a 5-bit word length characters.
Set 1: A Parity bit is generated (transmit data) or checked (receive data) between the
character.
These two specify the number of bits in each transmitted or received serial character.

transmission has to be restored.
During the break, the Transmitter can be used as a character timer to
accurately establish the break duration.
last data word bit and Stop bit of the serial data. (The Parity bit is used to
produce an even or odd number of 1s when the data word bits and the Parity
bit are summed.)
Two stop bits are generated for either 6-, 7-, or 8-bit word length characters.
The receiver checks the first Stop bit only, regardless of the number of Stop
bits selected.
