Channel 2 overcurrent threshold set to Ilim = (∆I(LDA), max · n · k), n from 0 to 255 0xFF Channel 2 overcurrent threshold set to the maximum current Table 54: Overcurrent threshold configuration channel 2 It is possible to use a second photodiode connected to channel 2 (e.g. as a safety supervisor). The ADC on channel 2 can be used to monitor the voltage at pin MDK2, as it is shown in figure 12.
