Bit
Name
Function
7CALZ
Clear ADC Calibration.
0 = Normal operation.
1 = Clears the existing calibration data. This bit must be written back to 0 after being set.
6MCAL
Manual ADC Calibration.
0 = No calibration.
1 = Initiate manual ADC calibration.
5CALD
ADC Auto-Calibration Disable.
0 = Enable auto-calibration.
1 = Disable auto-calibration.
4
Reserved Read returns 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.
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.
1ROV
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.
0BTD
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.
