The SPI is capable of detecting a mode fault when it is configured in master mode and NPCS0,
MOSI, MISO, and SPCK are configured as open drain through the I/O Controller with either
internal or external pullup resistors. If the I/O Controller does not have open-drain capability,
mode fault detection must be disabled by writing a one to the Mode Fault Detection bit in the MR
