Select Odd parity and the parity bit value is set to 0 or 1, based on data, to ensure that an odd number of
1 bits are contained in the coded character.
•
Select Even parity and the parity bit value is set to 0 or 1, based on data, to ensure that an even number
of 1 bits are contained in the coded character.
•
Select Mark parity and the parity bit is always 1.
•
Select Space parity and the parity bit is always 0.
•
Select None when no parity bit is required.
