We have literally tens of thousands of the MC9RS08KA2 in stock so Im trying to continue using it for a product upgrade. The problem that im facing is that i need one more input.
My hope was to put two push buttons with in parallel on this pin. pusing one would give 0 volts and the second would give 2.5v and the pin would normall rest at 5 volts if no button was pressed.
I know that the reset can only be used as a Input but is is possible for it to detect different voltage levels?
The IC will be pre programmed so I will not need the reset and or VPP.
