For More Information On This Product,
Framing error bit (FE) — FE is set when a logic 0 occurs where the
receiver expects a stop bit. The framing error interrupt enable bit,
FEIE, enables FE to generate SCI error CPU interrupt requests.
FE is in SCI status register 1. FEIE is in SCI control register 3.
Parity error bit (PE) — PE is set when the SCI detects a parity
error in incoming data. The parity error interrupt enable bit, PEIE,
enables PE to generate SCI error CPU interrupt requests. PE is in
SCI status register 1. PEIE is in SCI control register 3.
