Chapter 20 Serial Communication Interface (S12SCIV5)
20.1.2 Features
The SCI includes these distinctive features:
⢠Full-duplex or single-wire operation
⢠Standard mark/space non-return-to-zero (NRZ) format
⢠Selectable IrDA 1.4 return-to-zero-inverted (RZI) format with programmable pulse widths
⢠13-bit baud rate selection
⢠Programmable 8-bit or 9-bit data format
⢠Separately enabled transmitter and receiver
⢠Programmable polarity for transmitter and receiver
⢠Programmable transmitter output parity
⢠Two receiver wakeup methods:
â Idle line wakeup
â Address mark wakeup
⢠Interrupt-driven operation with eight flags:
â Transmitter empty
â Transmission complete
â Receiver full
â Idle receiver input
â Receiver overrun
â Noise error
â Framing error
â Parity error
â Receive wakeup on active edge
â Transmit collision detect supporting LIN
â Break Detect supporting LIN
⢠Receiver framing error detection
⢠Hardware parity checking
⢠1/16 bit-time noise detection
20.1.3 Modes of Operation
The SCI functions the same in normal, special, and emulation modes. It has two low power modes, wait
and stop modes.
