These bits are used to offset the phase of the Timing NCO. The range is 0 to 1 times the resampler input
period interpreted either as ± T/2 (2’s complement) or 0 to T (offset binary). Bit 7 is the MSB. This location
is a holding register. After loading, a transfer to the Active Register is done by writing to Control Word 15
or by generating a SYNCIN2 with Control Word 11, Bit 5 set to 1.
Writing to this address updates the active timing NCO Frequency Register in the timing NCO (see Timing
NCO Section).
Writing to this address updates the active timing NCO Phase Offset Register in the timing NCO (see
Timing NCO Section).

it won’t finish and if the sync is programmed to follow the data, there may never be a sync.
