Section 13. Serial Communications Interface Module (SCI)  
13.1 Introduction  
13.2 Features  
This section describes the serial communications interface module (SCI,  
version D), which allows high-speed asynchronous communications with  
peripheral devices and other microcontroller units (MCUs).  
Features of the SCI module include:  
Full-duplex operation  
Standard mark/space non-return-to-zero (NRZ) format  
32 programmable baud rates  
Programmable 8-bit or 9-bit character length  
Separately enabled transmitter and receiver  
Separate receiver and transmitter CPU interrupt requests  
Separate receiver and transmitter  
Programmable transmitter output polarity  
Two receiver wakeup methods:  
Idle line wakeup  
Address mark wakeup  
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
