This function aims to detect lock dialing num-
bers to prevent from an unauthorized long dis-
tance call. The dialing output of this chip is
disabled if the first input key after on-off hook is

abled.

When HFO is high, the Hand-free function is
enabled and can be reset by:
Off-hook
Applying a rising edge to HFI
Changing the HDO pin from low to high
