Differnce between “Simple SPI” and “Standalone SPI”?

  • 0

I have noticed that e2studio uses the term “simple SPI” for the SCI peripherals.  I am setting up a new board where I need two SPI connections for my RA4M3 board.  One to some motor drivers and one to non-QSPI external flash.  I will use the one “standalone SPI” that is available, and then one of the SCI peripherals.

Are there any constraints I need to worry about?

      The "simple SPI" mode of the SCI is significantly different than the SPI peripheral. For example the simple-SPI is limited to only 8-databits while the standalone-SPI supports many different bit lengths.  If your needs are met by what the simple-SPI supports there is no reason to avoid to using it.
