If using interrupts:
a)

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.

Clear the SMP bit.
If the CKE bit is set, then the SSEN bit must be
set, thus enabling the SSx pin.
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>).
Clear the SPIxIF bit in the respective IFS
register.
Set the SPIxIE bit in the respective IEC
register.
Write the SPIxIP bits in the respective IPC
register to set the interrupt priority.
