Measurement of AC signals via DC levelmeter
This method is applicable for a single frequency sinusoidal AC signal which is
superimposed on a DC signal.
1. Set the ring frequency f
2. Set the offset registers OFR1 and OFR2 to 0x00.
3. Measure the DC content with disabled rectifier (bit LM-RECT = 0).
4. The offset registers OFR1 and OFR2 have to be programmed to the value
5. Repeating the measurement of the DC content should result in a LM
6. Perform a new measurement with the rectifier enabled (bit LM-RECT = 1). The result

disturb the DC regulation and the off-hook indication. In active mode you can
freeze the output of the DC loop by setting the bit LM-HOLD to '1'. In ringburst
mode it is possible that DuSLIC automatically switches back to ringpause mode
because the measurement result was interpreted as off-hook. This can be avoided
by programming the off-hook current to the maximum value (79.66 mA).
