This register establishes the sensitivity of the NS rejection filter setting. NS is a measure of the line frequency. If a line
cycle occurs that is shorter or longer than the line cycle represented in the NS register, this filter determines whether
the cycle is used to update the NS value. For more information, see the NS register description. If this register is
zero, noise rejection is disabled for the line cycle counter.
This register determines whether the NS value is averaged over previous values or whether the most recently measured
value is used directly. If the value of this register is nonzero, the NS value is averaged using the following formula:
If the value of this register is zero, NS is not averaged. The MSB of this register must be zero.
