6.14.3 Serial Communications Interface (SCI)

The SCI is a 2-wire asynchronous serial port, commonly known as a UART. The SCI module supports digital communications between the CPU and other asynchronous peripherals that use the standard non-return-to-zero (NRZ) format

The SCI receiver and transmitter each have a 16-level-deep FIFO for reducing servicing overhead, and each has its own separate enable and interrupt bits. Both can be operated independently for half-duplex communication, or simultaneously for full-duplex communication. To specify data integrity, the SCI checks received data for break detection, parity, overrun, and framing errors. The bit rate is programmable to different speeds through a 16-bit baud-select register.

Features of the SCI module include:

  • Two external pins:
    • SCITXD: SCI transmit-output pin
    • SCIRXD: SCI receive-input pin
    • Baud rate programmable to 64K different rates
  • Data-word format
    • 1 start bit
    • Data-word length programmable from 1 to 8 bits
    • Optional even/odd/no parity bit
    • 1 or 2 stop bits
  • Four error-detection flags: parity, overrun, framing, and break detection
  • Two wake-up multiprocessor modes: idle-line and address bit
  • Half- or full-duplex operation
  • Double-buffered receive and transmit functions
  • Transmitter and receiver operations can be accomplished through interrupt-driven or polled algorithms with status flags.
    • Transmitter: TXRDY flag (transmitter-buffer register is ready to receive another character) and TX EMPTY flag (transmitter-shift register is empty)
    • Receiver: RXRDY flag (receiver-buffer register is ready to receive another character), BRKDT flag (break condition occurred), and RX ERROR flag (monitoring four interrupt conditions)
  • Separate enable bits for transmitter and receiver interrupts (except BRKDT)
  • NRZ format
  • Auto baud-detect hardware logic
  • 16-level transmit and receive FIFO

Note:

All registers in this module are 8-bit registers. When a register is accessed, the register data is in the lower byte (bits 7–0), and the upper byte (bits 15–8) is read as zeros. Writing to the upper byte has no effect.

Figure 6-68 shows the SCI block diagram.
