Write the desired settings to the SPIxCON1
and
(SPIxCON1<5>) = 1.
Clear the SPIROV bit (SPIxSTAT<6>).
Select Enhanced Buffer mode by setting the
SPIBEN bit (SPIxCON2<0>).
Enable SPI operation by setting the SPIEN bit
(SPIxSTAT<15>).
Write the data to be transmitted to the SPIxBUF
register. Transmission (and reception) will start
as soon as data is written to the SPIxBUF
register.
