LM-AC is a 4-bit nibble which contains K
CG1 is a 4-bit nibble that is calculated by DuSLICOS and which controls the conference
gain (see DuSLICOS byte file). To ensure that CG1 is not changed, please perform a
read/modify/write operation.

The integration function accumulates and sums up the level meter values over a set time
period. The time period from 1*16 ms to 16*16 ms is set by the bits LM-ITIME[3:0] in
register LMCR3. The integration function can be turned on and off by bit LM-EN in
register LMCR1.

The level can be calculated by:
The result registers get frequently updated after an integration period, if bit LM-EN in
register LMCR1 = 1. If the bit LM-ONCE in register LMCR1 is set to 1 then the integration
is executed only once. To start again, bit LM-EN must be changed from 0 to 1.
The level meter result can be transferred to the PCM/IOM-2 Interface, depending on bit
LM2PCM in register LMCR1.
Measurement of Currents via ITAC
To take current measurements via pin ITAC, all feedback loops (IM-filters and TH-filters)
should be disabled. To simplify the formulas, the programmable receive and transmit
gain is disabled.
This is done by setting the following bits:
