This read-only bitfield is reserved and always has the value zero.
Word N width
Configures the number of bits in each word, for each word except the first in the frame. The value written
should be one less than the number of bits per word. This field must be configured greater than or equal
to Word 0 Width even when there is only one word in each frame. Words of fewer than 8 bits wide are not
supported.
This read-only bitfield is reserved and always has the value zero.
Word 0 width
Configures the number of bits in the first word in each frame. The value written should be one less than
the number of bits in the first word. Words of less than 8 bits wide are not supported if there is only one
word per frame.
This read-only bitfield is reserved and always has the value zero.
First bit shifted
Configures the bit index for the first bit transmitted for each word in the frame. If configured for MSB First,
the index of the next bit transmitted is one less than the current bit transmitted. If configured for LSB First,
the index of the next bit transmitted is one more than the current bit transmitted. The value written should
be greater than or equal to the word width when configured for MSB First. The value written should be
less than or equal to 31-word width when configured for LSB First.
