Description
Channels
These bits indicate the number of channels in each
system word. These bits are ignored if CPEN = 1.
00: 1 channel per system word
01: 2 channels per system word
10: 3 channels per system word
11: 4 channels per system word
Data Word Length
These bits indicate the number of bits in a data word.
These bits are ignored if CPEN = 1.

Serial Bit Clock Direction
0: Serial clock input, slave mode
1: Serial clock output, master mode
Note: In non-compressed mode (SSICR.CPEN=0), the
combination of (SCKD, SWSD) = (0, 0) or (1, 1) is
available.
