USER’S MANUAL

MODF — Mode Fault Flag

0 = Normal operation.

1 = Another SPI node requested to become the network SPI master while the SPI

was enabled in master mode (SS input taken low).

The SPI asserts MODF when the SPI is in master mode (MSTR = 1) and the SS input

pin is negated by an external driver.

D.7.15 SPI Data Register

UPPB — Upper Byte

In 16-bit transfer mode, the upper byte contains the most significant eight bits of the

transmitted or received data. Bit 15 of the SPDR is the MSB of the 16-bit data.

LOWB — Lower Byte

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 eight bits of the data.
