2.19.24 SERCOM-SPI: Hardware Client Select Control

When the hardware client select control is enabled (CTRLB.MSSEN=1), the client select (SS) pin goes high after each byte transfer even if new data is ready to be sent.

Work Around:

Set CTRLB.MSSEN=0, and handle the client select (SS) pin by software.
