This read-only bitfield is reserved and always has the value zero.
Frame size
Configures the number of words in each frame. The value written should be one less than the number of
words in the frame (for example, write 0 for one word per frame). The maximum supported frame size is
16 words.
This read-only bitfield is reserved and always has the value zero.
Sync width
Configures the length of the frame sync in number of bit clocks. The value written should be one less than
the number of bit clocks (for example, write 0 for the frame sync to assert for one bit clock only). The sync
width cannot be configured longer than the first word of the frame.
This read-only bitfield is reserved and always has the value zero.
MSB first
Specifies whether the LSB or the MSB is transmitted/received first.
