BYTE 1
READ SCDR
READ SCS1
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 SCC3 is also set. Clear the PE bit by reading SCS1
with PE set and then reading the SCDR. Reset clears the PE bit.
