Serial Peripheral Interface (SPI)
20.14.2 SPI Status and Control Register
Technical Data
324
SPE — SPI Enable
SPTIE— SPI Transmit Interrupt Enable
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:
Freescale Semiconductor, Inc.
This read/write bit enables the SPI module. Clearing SPE causes a
partial reset of the SPI. See
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.
