I am facing the following problem: Pin D3 is set low with istruction "io(po,0,0)" and it does switch to low.
Then I want to read the pin status using instruction "VV = io(pi,0)" and VV is equal to 1 and the pin is ON as well. Readind status of pin D7 the pin remains stable and the logic value reported by "io(pi,13)" is correct.

At the moment I must avoid to read status of the pin D3 to avoid to turn on the pin when it should not.

OK! Understood the problem. Reading the input with instruction "io(pi,d3)" make the pin an input pin, so the pullup resistor switch the pin to logic 1. This means I have to take track of the output status using a status variable and refer to this variable all the time I need to know the logic status of my output.
I have also learned that d3 is critical when used as an output! So I will swap pins and use d3 as imput and d6 as output.
