The SPI module generates an interrupt indicating com-
pletion of a byte or word transfer, as well as a separate
interrupt for all SPI error conditions.

Both SPI1 and SPI2 can trigger a DMA
data transfer. If SPI1 or SPI2 is selected
as the DMA IRQ source, a DMA transfer
occurs when the SPI1IF or SPI2IF bit gets
set as a result of an SPI1 or SPI2 byte or
word transfer.
