PF — Parity Error Flag
Read anytime. Write has no meaning or effect.
SCSWAI — Serial Communications Interface Stop in WAIT Mode
RAF — Receiver Active Flag
(1)
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.
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).
If enabled with RIE = 1, RAF set generates an interrupt when
VDDPLL is high.
for descriptions of these bits.
0 = Parity correct
1 = Incorrect parity detected
0 = SCI clock operates normally.
1 = Halt SCI clock generation when in WAIT mode.
0 = A character is not being received
1 = A character is being received
