Default
Bit 7: Low-Frequency Input Clock Noise Window (NW). For 2kHz, 4kHz, or 8kHz input clocks, this configuration
bit enables a ±5% tolerance noise window centered around the expected clock edge location. Noise-induced edges
outside this window are ignored, reducing the possibility of phase hits on the output clocks. This only applies to the
T0 DPLL and should be enabled only when the T0 DPLL is locked to an input and the 180° phase detector is being
used.

0 = All edges are recognized by the T0 DPLL.
