18.14.2 SPI Status and Control Register
MC68HC908AS60 — Rev. 1.0
SPE — SPI Enable Bit
SPTIE — SPI Transmit Interrupt Enable Bit
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:
This read/write bit enables the SPI module. Clearing SPE causes a
partial reset of the SPI. (See
the SPE bit.
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.
