Clear ADC Calibration.
0 = Normal operation.
1 = Clears the existing calibration data. This bit must be written back to 0 after being set.
Manual ADC Calibration.
0 = No calibration.
1 = Initiate manual ADC calibration.
ADC 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.
When set, the DAA can detect a billing tone signal on the line and maintain on off-hook state
through the billing tone. If a billing tone is detected, the BTD bit (Register 17) is set to indicate
the event. Writing this bit to zero clears the BTD bit.
0 = Billing tone detection disabled. The BDT bit is not function.
1 = Billing tone detection enabled. The BDT is 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 zero 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 a billing tone is detected. Writing a zero to BTE clears this bit.
0 = No billing tone detected.
1 = Billing tone detected.
