I am trying to understand HAL configuration. Can you please help about this:

For example I am looking at these line in my HAL file:

net y-enable hm2_5i25.0.7i76.0.0.output-03

net y-enable <= axis.1.amp-enable-out
net y-enable => hm2_5i25.0.stepgen.01.enable


I think I can see that axis.1.amp-enable-out is connect to to net y-enable and that also connect to hm2_5i25.0.stepgen.01.enable and also connect same (of those 3way net) to hm2_5i25.0.7i76.0.0.output-03.

My question is there way to make hm2_5i25.0.7i76.0.0.output-03 into open collector/drain type?

I saw "is_opendrain" in HOSTMOT manual, but it looks like only for full GPIO pin.
And if that will works for 7i76 pin that I will use to enable external driver amp then what is syntax?

would it look like: hm2_5i25.0.7i76.0.0.output-03-is-opendrain or something else or not possible?

And if that will work then when y-enable == true then 7i76 03 is HiZ and when y-enable == false 7i76 03 is GND ?
or
If "is_opendrain" is not possible then when y-enable == true then 7i76 03 is +VField and when y-enable == false 7i76 03 is GND ?

Thanks!

No, the field outputs on the 7I76 are sourcing only
(They supply the field voltage when on and are open when off)
