Value Description
31–4 Reserved – 0 Reserved. The reserved bit location is always read as 0. A
value written to this field has no effect.
3–1 PRECISION 0–7h Precision bits determine the resolution of the interpolation. The
PRECISION bits can only be written when the GO bit is cleared
to 0. If the GO bit is set to 1, a write to the PRECISION bits
does not change the bits.
16BITS 0 16 bits
15BITS 1 15 bits
14BITS 2h 14 bits
