Freescale Semiconductor
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
