Figure
The diagram may be interpreted as a master or slave timing diagram where the SCK pin, the
MISO pin, the MOSI pin are directly connected between the master and the slave device.
If CPOL is changed at the communication byte boundaries, the SPI must be disabled by
resetting the SPE bit.

Master mode fault (MODF)
Master mode fault occurs when the master device has its SS pin pulled low.
When a Master mode fault occurs:
Clearing the MODF bit is done through a software sequence:
– The MODF bit is set and an SPI interrupt request is generated if the SPIE bit is set.
– The SPE bit is reset. This blocks all output from the Device and disables the SPI
– The MSTR bit is reset, thus forcing the Device into slave mode.
