Enhanced Serial Communications Interface (ESCI) Module
FE — Receiver Framing Error Bit
PE — Receiver Parity Error Bit
128
This clearable, read-only bit is set when a 0 is accepted as the stop bit. FE generates an ESCI error
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.
This clearable, read-only bit is set when the ESCI detects a parity error in incoming data. PE generates
a PE 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.
1 = Framing error detected
0 = No framing error detected
1 = Parity error detected
0 = No parity error detected
