PEIE — Receiver Parity Error Interrupt Enable Bit
SCI status register 1 contains flags to signal these conditions:
SCTE — SCI Transmitter Empty Bit

This read/write bit enables SCI receiver CPU interrupt
requests generated by the parity error bit, PE. (See

This clearable, read-only bit is set when the SCDR transfers a
character to the transmit shift register. SCTE can generate an SCI
transmitter CPU interrupt request. When the SCTIE bit in SCC2 is set,
SCTE generates an SCI transmitter CPU interrupt request. In normal
1 = SCI error CPU interrupt requests from PE bit enabled
0 = SCI error CPU interrupt requests from PE bit disabled
