Low cut-off function
Default configured for 1111 s (0.0009 Hz) or 2 s (0.5 Hz) with L.COF enabled. Drives input to 0 Hz when Low Cut-Off time is
reached.
For the frequency output of 4225C, an output low cut-off can be configured independently of the input low cut-off.
The LO.CUT point can be configured between output low and output hi frequency.
