AC Ring Trip Detect Threshold.
Programs the ac loop current threshold value above which a valid ring trip event is
detected. See "Ring Trip Detection" on page 39 for recommended values.
DC Ring Trip Debounce Interval.
Programs the debounce interval for the dc loop current detection circuit. 0 to 40.96 s
programmable range, 1.25 µ s/LSB. Refer to "Ring Trip Detection" on page 39 for
recommended values.
DC Ring Trip Detect Threshold.
Programs the dc loop current threshold value above which a valid ring trip event is
detected. See “Ring Trip Detection” for recommended values.
