Selects whether to add a parity bit to transmit data and
to check the parity of receive data, in asynchronous

added nor checked, regardless of the PE setting.

Notes: 1. If even parity is selected, the parity bit is
added to transmit data to make an even
number of 1s in the transmitted character
and parity bit combined. Receive data is
checked to see if it has an even number of
1s in the received character and parity bit
combined.
