13.14.1 SPI Control Register
The SPI control register does the following:
Address: $001B
Read:
Write:
Reset:
SPRIE — SPI Receiver Interrupt Enable 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.
DMAS —DMA Select Bit
This read-only bit has no effect on this version of the SPI. This bit
always reads as a 0.
SPMSTR — SPI Master Bit
MC68HC708MP16
Rev. 3.1
Freescale Semiconductor
Enables SPI module interrupt requests
Selects CPU interrupt requests
Configures the SPI module as master or slave
Selects serial clock polarity and phase
Configures the SPSCK, MOSI, and MISO pins as open-drain
outputs
Enables the SPI module
