Clear ADC Calibration.
0 = Normal operation.
1 = Clears the existing ADC calibration data. This bit must be written back to 0 after being set.
Manual ADC Calibration.
0 = No calibration.
1 = Initiate manual ADC calibration.
Auto-Calibration Disable.
0 = Enable auto-calibration.
1 = Disable auto-calibration.
Overload Protect Enable.
0 = Disabled.
1 = Enabled.
The OPE bit should always be cleared before going off-hook.
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.
Receive Overload.
This bit is set when the receive input has an excessive input level (i.e., receive pin goes below
ground). Writing a 0 to this location clears this bit and the ROVI bit (Register 4, bit 6).
0 = Normal receive input level.
1 = Excessive receive input level.
Billing Tone Detected.
This bit is set if an event, such as a billing tone, causes a disruption in the line-side power
supply. Writing a zero to BTE clears this bit.
0 = No billing tone detected.
1 = Billing tone detected.
