Mode Fault Detection
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.
When a mode fault is detected, the MODF bit in the SPI_SR is set until the SPI_SR is read
and the SPI is disabled until re-enabled by bit SPIEN in the SPI_CR (Control Register).
By default, Mode Fault Detection is enabled. It is disabled by setting the MODFDIS bit in the
SPI Mode Register.
