Function

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.

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 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.

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.

1TGDM

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.

0POLM

Polarity Reversal Detect Mask (Si3011 and 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.
