First question asked Welcome!

I am currently working with the PSoC 4 and have experienced some odd behaviour when using port 6 for digital low/high logic monitoring. I am using a basic switch circuit with external inline and pull up, however when using a 10k inline and the switch is pressed is driven low for some reason the input only drops to 4.4V whereas this should be 0V. 

I have used the same circuit on different ports on the PSoC 4 and it works fine. When you update the 10k inline resistor to 1k the port then works fine in line with all the others. To me this suggests that 10k inline is too strong and is not allowing the port to discharge.

Is this something anyone else has witnessed or knows that port 6 has certain requirements when using this resistor configuration.

Hello @Trollie 

Could you please let me know exactly which PSoC 4 MCU you are using?
Also, how have you configured the pin in your design?

Best Regards
Ekta
