 Hello
I am using the psoc UC that I have attached picture of.
My quistion. Can I use P1.1 and P1.0 as analog inputs? Right now I have set them up to be analog inputs only to check if the port is high or not (checking for a button to be pushed). Though it seems that it fails now and then, and I cant find a failure in the code, and worked long time with it. Is it wrong of me to check these ports for high or low using: "if (PRT1DR & pin1{}"?

Select: globalinodd
Drive: high z

Thanks in advance
