2.19.22 SERCOM-SPI: Data Preload
In SPI Client mode and with Client Data Preload Enabled (CTRLB.PLOADEN=1), the
first data sent from the client will be a dummy byte if the host cannot keep the client
select (SS) line low until the end of transmission.
Work Around:
In SPI Client mode, the client select (SS) pin must be kept low by the host until the
end of the transmission if the client data preload feature is used
(CTRLB.PLOADEN=1).
