•

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

Modes of Operation

The SCI functions the same in normal, special, and emulation modes. It has two low power modes, wait

and stop modes.

•

Run mode

•

Wait mode

•

Stop mode
