If the first stage notch filter frequency has been set
(Pn408.0 = 1), the second stage notch filter frequency
(Pn 40C) will automatically be updated.
Notes:
• If the first stage or the second stage notch filter
frequency has already been set (Pn408 = n.11),
the notch filter frequency cannot be set.
• If the frequency detected by this function is not
used, set the notch filter to be invalid (Pn408.0 =
0).
