full-duplex, asynchronous, NRZ serial communication between 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
Serial Communications Interface (SCI)
Figure 17-2
shows the structure of the SCI module. The SCI allows
for a summary of the input/output (I/O) registers.
