DAA Watchdog Timer Enable.
0 = Watchdog timer disabled.
1 = Watchdog timer enabled. When set, this bit is cleared only by a hardware reset. The
watchdog timer monitors DAA register writes. If a register write does not occur within a
4.096 second window, the DAA is put into an on-hook state. Only a write of a DAA regis-
ter restarts the timer.
Analog Loopback.
0 = Analog loopback mode disabled.
1 = Enables external analog loopback mode.
Ring Detect Mode.
0 = Ring detect on positive threshold.
1 = Ring detect on positive and negative threshold.
Hybrid Enable.
0 = Disconnects hybrid in transmit path.
1 = Connects hybrid in transmit path.
Receive Enable.
0 = Receive path disabled.
1 = Enables receive path.
Always write this bit to zero. Reads undefined.
