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
•
16-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
