Continuous selection format
Some peripherals must be deselected between every transfer. Other peripherals must remain selected
between several sequential serial transfers. The continuous selection format provides the flexibility to
handle both cases. The continuous selection format is enabled for the SPI configuration by setting the
CONT bit in the SPI command.
When the CONT bit = 0, the DSPI drives the asserted chip select signals to their idle states in between
frames. The idle states of the chip select signals are selected by the PCSIS field in the DSPI
