Must be zero.
6MCAL
Manual Calibration.
0 = No calibration.
1 = Initiate calibration.
5CALD
Auto-Calibration Disable.
0 = Enable auto-calibration.
1 = Disable auto-calibration.
4LIM
Current Limit
This bit only affects chip operation when the CTR21 dc termination mode is selected.
0 = No current limiting in CTR21 mode.
1 = Enables current limiting in CTR21 mode. The dc termination will current limit before
60 mA.
3OPE
Overload Protect Enable.
0 = Disable overload protection.
1 = Enable overload protection.
The overload protection feature prevents damage to the DAA when going off-hook with
excessive line current or voltage. When off-hook, if OPE is set and LVCS = 11111, the dc ter-
mination is disabled (800
Ω presented to the line), the hookswitch current is reduced, and the
OPD bit is set. The OPE bit should be written ~25 ms after going off-hook; it should be written
to 0 to reset.
2BTE
Billing Tone Protect Enable.
0 = Disabled.
1 = Enabled.
When set, the Si3016 will automatically respond to a collapse of the line-derived power supply
during a billing tone event. When off-hook, if BTE = 1 and BTD goes high, the dc termination
is changed to present 800
Ω to the line, and the DCT pin stops tracking the receive input pin.
During normal operation, the DCT pin tracks the receive input.
1ROV
Receive Overload.
This bit is set when the receive input has an excessive input level (i.e., receive pin goes below
ground). This bit is cleared by writing a zero to this location.
0 = Normal receive input level.
1 = Excessive receive input level.
0BTD
Billing Tone Detected.
This bit will be set if a billing tone is detected. This bit is cleared by writing a zero to this loca-
tion.
0 = No billing tone detected.
1 = Billing tone detected.
