Ring Trip Detect Debounce Interval.
The value written to this register defines the minimum steady state debounce time. The
value may be set between 0 ms (0x00) to 159 ms (0x7F) in 1.25 ms steps. Default
value = 12.5 ms.
Read returns zero.
Loop Current Limit.
The value written to this register sets the constant loop current. The value may be set
between 20 mA (0x00) and 41 mA (0x07) in 3 mA steps.
