BYTE 1
READ IRSCS1
READ IRSCDR
PE — Receiver Parity Error Bit
SCRF = 1
Freescale Semiconductor, Inc.
This clearable, read-only bit is set when the SCI detects a parity error
in incoming data. PE generates an SCI error CPU interrupt request if
the PEIE bit in IRSCC3 is also set. Clear the PE bit by reading
IRSCS1 with PE set and then reading the IRSCDR. Reset clears the
PE bit.
