Freescale Semiconductor

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

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
