Chapter 11 Serial Communication Interface (S12SCIV5)
⢠Programmable transmitter output parity
⢠Two receiver wakeup methods:
â Idle line wakeup
â Address mark wakeup
⢠Interrupt-driven operation with eight flags:
â Transmitter empty
â Transmission complete
â Receiver full
â Idle receiver input
â Receiver overrun
â Noise error
â Framing error
â Parity error
â Receive wakeup on active edge
â Transmit collision detect supporting LIN
â 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.
⢠Run mode
⢠Wait mode
⢠Stop mode
11.1.4 Block Diagram
Figure 11-1 is a high level block diagram of the SCI module, showing the interaction of various function
blocks.
