NOTE:
SSOE — Slave Select Output Enable Bit
Setting the SSOE bit disables the mode fault detect function.
LSBFE — LSB-First Enable Bit
In SPIDR, the MSB is always bit 7 regardless of the LSBFE bit.
The SSOE bit and the DDRSP3 bit configure the SS pin as a
general-purpose input or a slave-select output. Reset clears SSOE.
The LSBFE enables data to be transmitted LSB first. Reset clears
LSBFE.
