PF — Parity Error Flag
Read: Anytime
Write: Has no meaning or effect
RAF — Receiver Active Flag
Address:
Indicates if received data’s parity matches parity bit. This feature is active only
when parity is enabled. The type of parity tested for is determined by the PT
(parity type) bit in SC0CR1.
This bit is controlled by the receiver front end. It is set during the RT1 time period
of the start bit search. It is cleared when an idle state is detected or when the
receiver circuitry detects a false start bit (generally due to noise or baud rate
mismatch).
0 = Parity correct
1 = Incorrect parity detected
0 = Character is not being received.
1 = Character is being received.
