The integration function can be turned on and off by bit LM-EN in register LMCR1.
The levelmeter 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 has to be set from 0 to 1.
The levelmeter source/result can be transferred to the PCM/IOM-2 interface, depending
on the bit LM2PCM in register LMCR1.

• Example for positive value of LM
LM-VAL-H = "0010 0100" = 0x24
LM-VAL-L = "1010 0101" = 0xA5

• Example for negative value of LM
LM-VAL-H = "1001 1001" = 0x99
LM-VAL-L = "0110 0010" = 0x62
