Serial Communications Interface Modules (SCI1 and SCI2)
NF — Noise Flag
FE — Framing Error Flag
PF — Parity Error Flag
The NF flag is set when the SCI detects noise on the receiver input.
NF is set during the same cycle as the RDRF flag but does not get set
in the case of an overrun. Clear NF by reading SCISR1 and then
reading SCIDRL. Reset clears NF.
The FE flag is set when a logic 0 is accepted as the stop bit. FE is set
during the same cycle as the RDRF flag but does not get set in the
case of an overrun. FE inhibits further data reception until it is cleared.
Clear FE by reading SCISR1 and then reading SCIDRL. Reset clears
FE.
The PF flag is set when PE = 1 and the parity of the received data
does not match its parity bit. Clear PF by reading SCISR1 and then
reading SCIDRL. Reset clears PF.
