TIP Ground Detect.
0 = The CO has grounded TIP, causing current to flow. When current ceases to flow, this bit
returns to a one.
1 = The CO has not grounded TIP causing current to flow.
TIP Ground Detect Enable.
0 = The external relay connecting TIP to an isolated supply is closed, enabling current to flow
in TIP if the CO grounds TIP.
1 = The external relay connecting TIP to an isolated supply is open. In this state, the DAA is
unable to determine if the CO has grounded TIP.
Ring Ground.
0 = The external relay connecting RING to ground is closed, causing current to flow in RING.
1 = The external relay connecting RING to ground is open, not allowing current to flow in
RING.
Read returns zero.
