Peripheral Description

The SPI uses a MibSPI Protocol by TI.

The MibSPI/SPI is a high-speed synchronous serial input/output port that allows a serial bit stream of programmed length (2 to 16 bits) to be shifted into and out of the device at a programmed bit-transfer rate. The MibSPI/SPI is normally used for communication between the microcontroller and external peripherals or another microcontroller.

Standard and MibSPI modules have the following features:

  • 16-bit shift register
  • Receive buffer register
  • 8-bit baud clock generator
  • SPICLK can be internally-generated (master mode) or received from an external clock source
    (slave mode)
  • Each word transferred can have a unique format.
  • SPI I/Os not used in the communication can be used as digital input/output signals
