PHAWORD[30:0]:
The Phase Word (PHAWORD[30:0]) bits are the output bus of the Phase Detector. This bus
outputs the result of the Phase Count Averaging function. Depending on the number of
samples included in the averaging, from 0 to 15 of the LSB(s) of the PHAWORD bus may
represent the fractional part of the average value while the 16 following bits hold the integer
part. This value can be used to externally implement in software the PLL filtering function
and bypass the Digital Loop Filter block.
