7CALZ
Clear ADC Calibration.
0 = Normal operation.
1 = Clears the existing ADC calibration data. This bit must be written back to 0 after being set.
6
MCAL
Manual ADC Calibration.
0 = No calibration.
1 = Initiate manual ADC calibration.
5CALD
Auto-Calibration Disable.
0 = Enable auto-calibration.
1 = Disable auto-calibration.
4RT2
Ringer Threshold Select 2. Si3018 and Si3019 line-side only.
This bit, in combination with the RT bit, is used to satisfy country requirements on ring detec-
tion. Signals below the lower level do not generate a ring detection; signals above the upper
level are guaranteed to generate a ring detection.

For Si3011 line-side device, always write this bit to zero.
3OPE
Overload Protect Enable.
0=Disabled.
1 = Enabled.
The OPE bit should always be cleared before going off-hook.
2BTE
Billing Tone Detect Enable.
The DAA can detect events, such as billing tones, that can cause a disruption in the line-side
power supply. When this bit is set, the device will maintain off-hook during such events. If a
billing tone is detected, the BTD bit (Register 17, bit 0) is set to indicate the event. Writing this
bit to zero clears the BTD bit.
0 = Billing tone detection disabled. The BTD bit is not functional.
1 = Billing tone detection enabled. The BTD bit is not functional.
