7
RDTM 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.
6
ROVM 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.
5
FDTM Frame Detect Mask.
0 = The ISOcap losing frame lock does not cause an interrupt on the AOUT/INT pin.
1 = The ISOcap losing frame lock causes an interrupt on the AOUT/INT pin.
4
BTDM 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.
3
DODM 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.
2 LCSOM ^{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.
1
TGDM TIP Ground Detect Mask.
0 = The TGD bit going active does not cause an interrupt on the AOUT/INT pin.
1 = The TGD bit going active causes an interrupt on the AOUT/INT pin.
0
POLM Polarity Reversal Detect Mask (Si3019 line-side only).
This interrupt is generated from bit 7 of the LVS register. When this bit transitions, it indicates
that the polarity of TIP and RING is 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.
