16.12 I/O Registers
Three registers control and monitor SPI operation:
16.12.1 SPI Control Register
The SPI control register:
SPRIE — SPI Receiver Interrupt Enable Bit
SPMSTR — SPI Master Bit
CPOL — Clock Polarity Bit
CPHA — Clock Phase Bit

This read/write bit enables CPU interrupt 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.
This read/write bit selects master mode operation or slave mode operation. Reset sets the SPMSTR
bit.
This read/write bit determines the logic state of the SPSCK pin between transmissions. (See
16-5
CPOL values. Reset clears the CPOL bit.
This read/write bit controls the timing relationship between the serial clock and SPI data. (See
16-5
CPHA values. When CPHA = 0, the SS pin of the slave SPI module must be high between bytes. (See
