Serial Communication Interface (S12SCIV5)
11.1.2 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:
— Idle line wakeup
— Address mark wakeup
•
Interrupt-driven operation with eight flags:
— Transmitter empty
— Transmission complete
— Receiver full
— Idle receiver input
— Receiver overrun
— Noise error
— Framing error
— Parity error
— Receive wakeup on active edge
— Transmit collision detect supporting LIN
— Break Detect supporting LIN
Receiver framing error detection
Hardware parity checking

•
1/16 bit-time noise detection
11.1.3 Modes of Operation
The SCI functions the same in normal, special, and emulation modes. It has two low power modes, wait
and stop modes.
