Parity
Defines the optional parity bit that is used for error detection.
"None"
No parity bit is used.
"Even"
The parity bit is set to "1" if the number of data bits set to "1" is odd.
Adding the parity bit makes the data word's parity even.
"Odd"
The parity bit is set to "1" if the number of data bits set to "1" is even.
Adding the parity bit makes the data word's parity odd.
