Description
MSB First/LSB First Select
Selects that the serial data is transmitted in MSB first or
LSB first.
0: LSB first
1: MSB first
Clock Polarity Select
Selects the SSCK clock polarity.
0: High output in idle mode, and low output in active
1: Low output in idle mode, and high output in active
Clock Phase Select (Only for SSU Mode)
Selects the SSCK clock phase.
0: Data changes at the first edge.
1: Data is latched at the first edge.
Reserved
These bits are always read as 0. The write value should
always be 0.
