SPI Features

  • Data transmits of 1 to 16 bits supported directly. Larger frames supported by software.
  • Master and slave operation.
  • Data can be transmitted to a slave without the need to read incoming data. This can be useful while setting up an SPI memory.
  • Control information can optionally be written along with data. This allows very versatile operation, including frames of any length.
  • One Slave Select input/output with selectable polarity and flexible usage.
Note: Texas Instruments SSI and Microwire modes are not supported.
