Serial Communication Interface (SCI)

The SCI has the following features:

  • Standard universal asynchronous receiver-transmitter (UART) communication
  • Supports full- or half-duplex operation
  • Standard non-return to zero (NRZ) format
  • Double-buffered receive and transmit functions in compatibility mode
  • Supports two individually enabled interrupt lines: level 0 and level 1
  • Configurable frame format of 3 to 13 bits per character based on the following:
    • Data word length programmable from one to eight bits
    • Additional address bit in address-bit mode
    • Parity programmable for zero or one parity bit, odd or even parity
    • Stop programmable for one or two stop bits
  • Asynchronous or iso-synchronous communication modes with no CLK pin
  • Two multiprocessor communication formats allow communication between more than two devices
  • Sleep mode is available to free CPU resources during multiprocessor communication and then wake up to receive an incoming message
  • Capability to use Direct Memory Access (DMA) for transmit and receive data
  • Five error flags and Seven status flags provide detailed information regarding SCI events
  • Two external pins: RS232_RX and RS232_TX
  • Multi-buffered receive and transmit units
