Ring Trip Low-pass Filter Coefficient.
Programs the low-pass filter coefficient used in the ring trip detection circuit. See
“4.8. Ring Trip Detection” for recommended values.
DC Settling Speedup Timer.
Programs the dc speedup timer that allows quicker settling during loop transitions.
This timer is invoked by the common-mode threshold detectors, CMHITH and
CMLOTH. 1.25 ms/LSB, exception: 0x0000 = 60 ms (default).
Ringing Speedup Timer.
Programs the dc speedup timer that allows quicker settling following ringing bursts.
This timer is invoked by any mode change from the ringing state. 40.96 s range,
1.25 ms/LSB, exception: 0x0000 = 60 ms (default).
