Serial Communications Interface Module (SCI)
11.1 Introduction
The MC68HC908AP64 has two SCI modules:
This section describes SCI1, the serial communications interface (SCI) module, which allows high-speed
asynchronous communications with peripheral devices and other MCUs.
11.2 Features
Features of the SCI module include the following:

SCI1 is a standard SCI module, and
SCI2 is an infrared SCI module.
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
Configuration register bit, SCIBDSRC, to allow selection of 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
When the SCI is enabled, the TxD pin is an open-drain output and requires
a pullup resistor to be connected for proper SCI operation.
