extra SPI using FlexIO

[gschelotto]

Hi,

I have to implement 3 independent 4-wire SPI master channels on MKL17Z. Just to be sure, is it possible to do it using SPI0, SPI1 and FlexIO without constraints? If so, can I use any FlexIO port (from D0 to D7) to implement the extra SPI channel?

regards,

gaston

Hi Gaston Schelotto,

     SPI0, SPI1 and FlexIO are the different modules, so you can use these modules as SPI functions, no constraints.

    About the flexIO pin, you can use any FlexIO port to implement the extra SPI channel:

Wish it helps you!

Have a great day,
Kerry
