IO_OUTP_CTRL 1-2
The Polarity flag determines whether the output is low active (0) or high active (1). The output
mode can be seen in the following table. The current status of the output and be queried and set
via the PinState flag.

Table 77: Output ID
The “Polarity“ setting refers to the input side of the inverting optical coupler output, “PinState
0” switches off the output transistor and produces high level over the resistor.
