Serial Communications Interface (SCI)
• Two receiver wake-up methods:
– Idle line wake-up
– Address mark wake-up
• Interrupt-driven operation with eight flags:
– Transmitter empty
– Transmission complete
– Receiver full
– Idle receiver input
– Receiver overrun
– Noise error
– Framing error
– Parity error
• Receiver framing error detection
• Hardware parity checking
• 10/13 bit software selectable break character length
• 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
Normal mode of operation.
Wait Mode
SCI operation in wait mode depends on the state of the SCISWAI bit in
the SCI control register 1 (SCIxCR1).
• If SCISWAI is clear, the SCI operates normally when the CPU is
in wait mode.
