MISO pin and 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.

Error flags
Master mode fault (MODF)
Master mode fault occurs when the master device’s SS pin is pulled low.
When a Master mode fault occurs:
●
●
●
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
peripheral.
The MSTR bit is reset, thus forcing the device into slave mode.
