scale (100%) current: E
For input and output current specifications, negative current is defined as coming out of (sourcing) the specified device pin.
A RESET pulse of this duration will reset the translator to the Home position without entering Sleep mode.
Current Trip Point Error is the difference between actual current trip point and the target current trip point, referred to full
