SCI Registers and Control Bits
NEIE â Noise Error Interrupt Enable
This bit enables the noise flag (NF) to generate hardware interrupt requests.
1 = Hardware interrupt requested when NF = 1.
0 = NF interrupts disabled (use polling).
FEIE â Framing Error Interrupt Enable
This bit enables the framing error flag (FE) to generate hardware interrupt requests.
1 = Hardware interrupt requested when FE = 1.
0 = FE interrupts disabled (use polling).
PEIE â Parity Error Interrupt Enable
This bit enables the parity error flag (PF) to generate hardware interrupt requests.
1 = Hardware interrupt requested when PF = 1.
0 = PF interrupts disabled (use polling).
11.10.7 SCI x Data Register (SCIxD)
This register is actually two separate registers. Reads return the contents of the read-only receive data
buffer and writes go to the write-only transmit data buffer. Reads and writes of this register are also
involved in the automatic ï¬ag clearing mechanisms for the SCI status ï¬ags.
