SPIF
SPIF Interrupt Flag — This bit is set after a received data byte has been transferred into the SPI Data Register.
This bit is cleared by reading the SPISR register (with SPIF set) followed by a read access to the SPI Data
Register.
0 Transfer not yet complete
1 New data copied to SPIDR
SPI Transmit Empty Interrupt Flag — If set, this bit indicates that the transmit data register is empty. To clear
this bit and place data into the transmit data register, SPISR has to be read with SPTEF = 1, followed by a write
to SPIDR. Any write to the SPI Data Register without reading SPTEF = 1, is effectively ignored.
0 SPI Data register not empty
1 SPI Data register empty
Mode Fault Flag — This bit is set if the SS input becomes low while the SPI is configured as a master and mode
fault detection is enabled, MODFEN bit of SPICR2 register is set. Refer to MODFEN bit description in
Section 9.3.2.2, “SPI Control Register 2 (SPICR2).”
Register (with MODF set) followed by a write to the SPI Control Register 1.
0 Mode fault has not occurred.
1 Mode fault has occurred.
