5.13.2 Line Status for Output Lines

This section informs about the relation between output line status and certain external conditions.
The opto-isolated and the GPIO output lines are considered.
The line status information depends, among others, on whether the output line inverter is disabled
or enabled (Section 5.12.5 on
parameter (Section 5.12.3 on
Two types of installation are considered (see

involved (A: "external pull-up resistor disconnected"; not useful for the opto-isolated output
line).
The output line is connected to the external power supply via an external pull-up resistor (B:

The output circuits display open collector circuit behavior. The GPIO lines are,
however, equipped with a weak internal pull up resistor.
Make sure the ground for opto-isolated I/O and the ground of the power supply for the opto-isolated
output line are connected to the same ground.
