RGF1, RGF2 and RGF3 are 4-bit nibbles which control the ring frequency f
RGA1 is a 4-bit nibble that is calculated by DuSLICOS and which controls the ringer
amplitude (see DuSLICOS byte file). To ensure that RGA1 is not changed, please
perform a read/modify/write operation.

The integration function can be turned on and off by bit LM-EN in register LMCR1.
The level meter result of the selected signal source will be stored in the result registers
LMRES1 (bits LM-VAL-H[7:0]) and LMRES2 (bits LM-VAL-L[7:0]) depending on the
LM-SEL[3:0] bits in register LMCR2. The result registers get frequently updated every
500 µs if bit LM-EN in register LMCR1 = 0, or 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 source/result can be transferred to the PCM/IOM-2 Interface, depending
on the bit LM2PCM in register LMCR1.
