Serial Peripheral Interface Module (SPI)
I/O registers
0 = Normal push-pull SPSCK, MOSI, and MISO pins
SPE — SPI enable
This read/write bit enables the SPI module. Clearing SPE causes a
partial reset of the SPI. See Resetting the SPI on page 231. Reset
clears the SPE bit.
1 = SPI module enabled
0 = SPI module disabled
SPTIE— SPI transmit interrupt enable
This read/write bit enables CPU interrupt requests or DMA service
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.
1 = SPTE CPU interrupt requests enabled
0 = SPTE CPU interrupt requests disabled
