7RDTM
Ring Detect Mask.
0 = A ring signal does not cause an interrupt on the AOUT/INT pin.
1 = A ring signal causes an interrupt on the AOUT/INT pin.
6ROVM
Receive Overload Mask.
0 = A receive overload does not cause an interrupt on the AOUT/INT pin.
1 = A receive overload causes an interrupt on the AOUT/INT pin.
5FDTM
Frame Detect Mask.
0 = The communications link achieving frame lock does not cause an interrupt on the AOUT/
INT pin.
1 = The communications link achieving frame lock causes an interrupt on the AOUT/INT pin.
4BTDM
Billing Tone Detect Mask.
0 = A detected billing tone does not cause an interrupt on the AOUT/INT pin.
1 = A detected billing tone causes an interrupt on the AOUT/INT pin.
3DODM
Drop Out Detect Mask.
0 = A line supply dropout does not cause an interrupt on the AOUT/INT pin.
1 = A line supply dropout causes an interrupt on the AOUT/INT pin.
2LCSOM
Loop Current Sense Overload Mask.
0 = An interrupt does not occur when the LCS bits are all 1s.
1 = An interrupt occurs when the LCS bits are all 1s.
1DLCSM
Delta Loop Current Sense Mask.
0 = An interrupt does not occur when the LCS bits change.
1 = An interrupt does occur when the LCS bits change.
0POLM
Polarity Reversal Detect Mask.
Generated from bit 7 of the LVS register. When this bit transitions, it indicates that the polarity
of TIP and RING was switched.
0 = A polarity change on TIP and RING does not cause an interrupt on the AOUT/INT pin.
1 = A polarity change on TIP and RING causes an interrupt on the AOUT/INT pin.
