MODF — Mode Fault Bit

SPIF is set upon completion of data transfer between the processor
and the external device. If SPIF goes high, and if SPIE is set, a serial
peripheral interrupt is generated. To clear the SPIF bit, read the SPSR
with SPIF set, then access the SPDR. Unless SPSR is read (with
SPIF set) first, attempts to write SPDR are inhibited.
Clearing the WCOL bit is accomplished by reading the SPSR (with
WCOL set) followed by an access of SPDR.
To clear the MODF bit, read the SPSR (with MODF set), then write to
the SPCR.
