Serial Communications Interface (SCI)
9.2 Introduction
The serial communications interface (SCI) module allows high-speed
asynchronous communication with peripheral devices and other
microcontroller units (MCU).
9.3 Features
Features of the SCI module include:
• Standard mark/space non-return-to-zero format
• Full duplex operation
• 32 programmable baud rates
• Programmable 8-bit or 9-bit character length
• Separately enabled transmitter and receiver
• Two receiver wakeup methods:
– Idle line wakeup
– Address mark wakeup
• Interrupt-driven operation capability with five interrupt flags:
– Transmitter data register empty
– Transmission complete
– Receiver data register full
– Receiver overrun
– Idle receiver input
• Receiver framing error detection
• 1/16 bit-time noise detection
