BitD7D6D5 D4 D3D2 D1 D0
Name
DVL AVL
Type R/W R/W
Bit Name Function
7:5 DVL Differential Voltage Level.
Differential voltage level to detect intrusion event (2.75 V units.)
4:0 AVL
Absolute Voltage Level.
Absolute voltage level to detect intrusion event (2.75 V units added to 3 V.)
S12 (OFHI). Off-Hook Intrusion
BitD7D6D5 D4 D3D2 D1 D0
Name
DCL ACL
Type R/W R/W
Bit Name Function
7:5 DCL Differential Current Level.
Differential current level to detect intrusion event (3 mA units.)
4:0 ACL
Absolute Current Level.
When S13[4] (OFHD) = 0
b
, ACL represents the absolute current threshold used by the
off-hook intrusion algorithm (3 mA units added to 12 mA.)
When OFHD = 1
b
, see "5.5.5.Differential Algorithm #2" on page 20.
