I would like to recreate this remapper with a slight modification.

What is PIC16LF1713-I SS doing

https://www.ebay.de/...3020655451

On the Remapper the chip "PIC16LF1713-I / SS" is installed. Only what exactly does he do? I have no idea about MiKroelektronik…

I know that the chip comes with a certain key press in a "programming mode" and then you will be able to "copy" buttons on the additional buttons on the Remapper?

Is there an easy way to read the schematic or does anyone have an idea how to get familiar with the topic quickly?
