Serial Peripheral Interface
19.5
The following sections describe programming examples of the SPI master and slave.
19.5.1
The following sequence initialize the SPI to run at a high speed in master mode:
19.5.2
The following is an example initialization sequence to follow when the SPI is in slave mode. It is very
similar to the SPI master example, except that SPISEL is used instead of a general-purpose I/O signal.

1. Configure a parallel I/O signal to operate as the SPI select output signal if needed.
2. Write 0xFFFFFFFF to SPIE to clear any previous events. Configure SPIM to enable all desired SPI
3. Configure SPMODE to enable normal operation (not loopback), master mode, SPI enabled,
4. Write the first character to be sent to SPITD.
