This clearable, read-only bit is set automatically on the eighth rising
edge on the PB7/SCK pin and indicates that a data transmission took
place. SPIF does not inhibit further transmissions. Clear SPIF by
reading the SIOP status register while SPIF is set and then reading or
writing the SIOP data register. Reset clears SPIF.
