16.2.5 Parity

Parity can be enabled to detect if a transmission was in error. This is done by counting the number of "1" bits in the frame. When using even parity the parity bit will be set if the total number of "1"s in the frame are an even number. If using odd parity the parity bit will be set if the total number of "1"s are odd.

When receiving a character the receiver will count the number of "1"s in the frame and give an error if the received frame and parity bit disagree.
