I am trying to build a shield for a Mega 2560. This shield is designed to Interface dual Hbridge, encoder and limit switches for linear actuators. With the limit switches I have decided to use a MC14490 Hex Contact Bounce Eliminator which requires the use of an oscillator and was hoping to use the internal oscillator via the (ICP3/CLKO/INT7) PE7 (I'm aware of the processes Fuse, Bootloaders, etc..). Here is the question I can find the (ICP3/CLKO/INT7) PE7 output on the Atmega2560 chip (pin9) but nowhere in the Pinout diagrams for the Arduino Mega 2560 can I find the actual pin to connect to, is there one? I found a reference on another site implying that a wire has to be soldered to the pin9 on the actual chip. Been trolling the internet but just seem to be going around in circles, hope someone has an answer.
