SPRIE — SPI Receiver Interrupt Enable Bit
This read/write bit enables CPU interrupt requests or DMA service
requests generated by the SPRF bit. The SPRF bit is set when a byte
transfers from the shift register to the receive data register. Reset
clears the SPRIE bit.
1 = SPRF CPU interrupt requests or SPRF DMA service requests
enabled
0 = SPRF CPU interrupt requests or SPRF DMA service requests
disabled
