PF — Parity Error Flag
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 SCxCR1.
0 = Parity correct
1 = Incorrect parity detected

$00C5/$00CD
Read anytime. Write has no meaning or effect.
SCSWAI — Serial Communications Interface Stop in WAIT Mode
0 = SCI clock operates normally.
1 = Halt SCI clock generation when in WAIT mode.
RAF — Receiver Active Flag
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 = A character is not being received
1 = A character is being received
If enabled with RIE = 1, RAF set generates an interrupt when
VDDPLL is high.
