Read returns zero.
Common Mode Calibration Error Interrupt.
This bit is set when off-hook/on-hook status changes during the common mode balance
calibration. Writing 1 to this bit clears a pending interrupt.
0 = No interrupt pending.
1 = Interrupt pending.
Indirect Register Access Serviced Interrupt.
This bit is set once a pending indirect register service request has been completed. Writ-
ing 1 to this bit clears a pending interrupt.
0 = No interrupt pending.
1 = Interrupt pending.
DTMF Tone Detected Interrupt.
Writing 1 to this bit clears a pending interrupt.
0 = No interrupt pending.
1 = Interrupt pending.
