Read returns zero.
Ring Trip/Loop Closure Unfiltered Output.
State of this bit reflects the realtime output of ring trip and loop closure detect circuits
before debouncing.
0 = Ring trip/loop closure threshold exceeded.
1 = Ring trip/loop closure threshold not exceeded.
Ring Trip Detect Indicator (Filtered Output).
0 = Ring trip detect has not occurred.
1 = Ring trip detect occurred.
Loop Closure Detect Indicator (Filtered Output).
0 = Loop closure detect has not occurred.
1 = Loop closure detect has occurred.
Read returns zero.
Loop Closure Debounce Interval.
The value written to this register defines the minimum steady state debounce time. Value
may be set between 0 ms (0x00) to 159 ms (0x7F) in 1.25 ms steps. Default value =
12.5 ms.
