NEIE — Receiver Noise Error Interrupt Enable Bit
FEIE — Receiver Framing Error Interrupt Enable Bit
PEIE — Receiver Parity Error Interrupt Enable Bit
7.8.4 SCI Status Register 1
SCI status register 1 (SCS1) contains flags to signal these conditions:
SCTE — SCI Transmitter Empty Bit
Freescale Semiconductor
This read/write bit enables SCI error CPU interrupt requests generated by the noise error bit, NE.
Reset clears NEIE.
This read/write bit enables SCI error CPU interrupt requests generated by the framing error bit, FE.
Reset clears FEIE.
This read/write bit enables SCI error CPU interrupt requests generated by the parity error bit, PE.

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 operation, clear the SCTE bit by
reading SCS1 with SCTE set and then writing to SCDR. Reset sets the SCTE bit.
1 = SCI error CPU interrupt requests from NE bit enabled
0 = SCI error CPU interrupt requests from NE bit disabled
1 = SCI error CPU interrupt requests from FE bit enabled
0 = SCI error CPU interrupt requests from FE bit disabled
1 = SCI error CPU interrupt requests from PE bit enabled
0 = SCI error CPU interrupt requests from PE bit disabled
1 = SCDR data transferred to transmit shift register
