BYTE 1
BYTE 1
READ SCS1
READ SCDR
PE — Receiver Parity Error Bit
SCRF = 1
This clearable, read-only bit is set when the SCI detects a parity error
in incoming data. PE generates a PE 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.
