The SPI asserts MODF when the SPI is in master mode (MSTR = 1) and the SS input
pin is negated by an external driver.
In 16-bit transfer mode, the upper byte is contains the most significant 8 bits of the
transmitted or received data. Bit 15 of the SPDR is the MSB of the 16-bit data.
In 8-bit transfer mode, the lower byte contains the transmitted or received data. MSB
in 8-bit transfer mode is bit 7 of the SPDR. In 16-bit transfer mode, the lower byte holds
the least significant 8 bits of the data.
0 = Normal operation.
1 = Another SPI node requested to become the network SPI master while the SPI
14
U
was enabled in master mode (SS input taken low).
