LCROFFHK[15:0]
Loop Closure Detection Threshold—On-Hook to Off-Hook Transition.
Programs the loop current threshold at which a valid loop closure is detected when
transitioning from on-hook to off-hook. Hysteresis is provided by programming the
ONHKTH RAM location to a different value that detects the off-hook to on-hook tran-
sition threshold. 0 to 101.09 mA programmable range, 3.097
A/LSB, 396.4 A
effective resolution. Usable range is 0 to 61 mA.
