    Also that device uses PPS so you need to make sure that you have mapped the signals to the pins correctly. For SPI peripherals without PPS, you sometimes also need to map the SCK single as both an input and an output to the same pin.
    Also look out for the 'standard' problems of making sure the pins are in 'digital' (and not 'analog') mode etc..
