Serial Peripheral Interface Module (SPI)
SPWOM — SPI Wired-OR Mode Bit
SPE — SPI Enable
SPTIE— SPI Transmit Interrupt Enable
13.13.2 SPI Status and Control Register
The SPI status and control register contains flags to signal these conditions:
The SPI status and control register also contains bits that perform these functions:
SPRF — SPI Receiver Full Bit

This read/write bit disables the pullup devices on pins SPSCK, MOSI, and MISO so that those pins
become open-drain outputs.
This read/write bit enables the SPI module. Clearing SPE causes a partial reset of the SPI. (See
Resetting the
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.

This clearable, read-only flag is set each time a byte transfers from the shift register to the receive data
register. SPRF generates a CPU interrupt request if the SPRIE bit in the SPI control register is set also.
During an SPRF CPU interrupt, the CPU clears SPRF by reading the SPI status and control register
with SPRF set and then reading the SPI data register. Reset clears the SPRF bit.
1 = Wired-OR SPSCK, MOSI, and MISO pins
0 = Normal push-pull SPSCK, MOSI, and MISO pins

0 = SPI module disabled
