FE — Receiver Framing Error Bit
PE — Receiver Parity Error Bit
Freescale Semiconductor
This clearable, read-only bit is set when a logic 0 is accepted as the stop bit. FE generates an SCI error
CPU interrupt request if the FEIE bit in SCC3 also is set. Clear the FE bit by reading SCS1 with FE set
and then reading the SCDR. Reset clears the FE bit.
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.
1 = Framing error detected
0 = No framing error detected
1 = Parity error detected
0 = No parity error detected
