Serial Peripheral Interface (SPI)
Technical Data

MODF — Mode Fault Bit
This clearable, read-only bit is set when a logic 0 occurs on the
PD5/SS pin while the MSTR bit is set. MODF generates an interrupt
request if the SPIE bit is also set. Clear the MODF bit by reading the
SPSR with MODF set and then writing to the SPCR. Reset clears
MODF.
