A mode fault is detected when the SPI is programmed in Master Mode and a low level is driven
by an external master on the NPCS0/NSS signal. In this case, multi-master configuration,
NPCS0, MOSI, MISO and SPCK pins must be configured in open drain (through the PIO control-
ler). When a mode fault is detected, the MODF bit in the SPI_SR is set until the SPI_SR is read
