DBIRAW 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.

1

RTP

Ring Trip Detect Indicator (Filtered Output).

0 = Ring trip detect has not occurred.

1 = Ring trip detect occurred.

LCR

Loop Closure Detect Indicator (Filtered Output).

0 = Loop closure detect has not occurred.

1 = Loop closure detect has occurred.

6:0

LCDI[6:0] 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.
