Serial Peripheral Interface (SPI)
17.13.2 SPI Status and Control Register (SPSCR)
Advance Information
276
SPE — SPI Enable
SPTIE— SPI Transmit Interrupt Enable
The SPI status and control register contains flags to signal the following
conditions:
This read/write bit enables the SPI module. Clearing SPE causes a
partial reset of the SPI. See Resetting the SPI. Reset clears the SPE
bit.
This read/write bit enables CPU interrupt requests generated by the
SPTE bit. SPTE is set when a byte transfers from the transmit data
register to the shift register. Reset clears the SPTIE bit.
