Serial Communications Interface (SCI)
7.1 Introduction
This section describes the serial communications interface (SCI) module, which allows high-speed
asynchronous communications with peripheral devices and other MCUs.
7.2 Features
Features of the SCI module include the following:
Freescale Semiconductor
•

•
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
Programmable transmitter output polarity
Two receiver wakeup methods:
–
–
Interrupt-driven operation with eight interrupt flags:
–
–
–
–
–
–
–
–
Receiver framing error detection
Hardware parity checking
1/16 bit-time noise detection
Bus clock as baud rate clock source
Idle line wakeup
Address mark wakeup
Transmitter empty
Transmission complete
Receiver full
Idle receiver input
Receiver overrun
Noise error
Framing error
Parity error
References to DMA (direct-memory access) and associated functions are
only valid if the MCU has a DMA module. This MCU does not have the DMA
function. Any DMA-related register bits should be left in their reset state for
normal MCU operation.
