11.1.1 Features
Features of SCI module include:
⢠Full-duplex, standard non-return-to-zero (NRZ) format
⢠Double-buffered transmitter and receiver with separate enables
⢠Programmable baud rates (13-bit modulo divider)
⢠Interrupt-driven or polled operation:
â Transmit data register empty and transmission complete
â Receive data register full
â Receive overrun, parity error, framing error, and noise error
â Idle receiver detect
⢠Hardware parity generation and checking
⢠Programmable 8-bit or 9-bit character length
⢠Receiver wakeup by idle-line or address-mark
⢠Optional 13-bit break character
⢠Selectable transmitter output polarity
11.1.2 Modes of Operation
See Section 11.3, âFunctional Description,â for a detailed description of SCI operation in the different
modes.
⢠8- and 9-bit data modes
⢠Stop modes â SCI is halted during all stop modes
⢠Loop mode
⢠Single-wire mode
11.1.3 Block Diagram
Figure 11-2 shows the transmitter portion of the SCI.
