Dither position, where dither inserted after NS.
0,1,2 = dither bits 2:0
4 = dither bits 3:1
5 = dither bits 4:1
....
19 = dither bits 19:17
1 = dither -1 to +1, 0 = -3 to +3
1 = disable dither
dvalue constant field
1 = swap pwm a/b output pair for all channels
The control lines to the power stage are swapped
inverting the output signal.
1 = tristate, 0 = binary
pwm output muxing
0 = normal
1 = swap 0/1
2 = ch0 on both
3 = ch1 on both
tristate constant field, must be even and not 0
