13.4 Functional Description
MC68HC908MR8 — Rev 4.1
Freescale Semiconductor
The SCI allows full-duplex, asynchronous, NRZ serial communication
among the MCU and remote devices, including other MCUs. The
transmitter and receiver of the SCI operate independently, although they
use the same baud rate generator. During normal operation, the CPU
monitors the status of the SCI, writes the data to be transmitted, and
processes received data.

Interrupt-driven operation with eight interrupt flags:
– Transmitter empty
– Transmission complete
– Receiver full
– Idle receiver input
– Receiver overrun
– Noise error
– Framing error
– Parity error
Receiver framing error detection
Hardware parity checking
1/16 bit-time noise detection
