We are using STM8L051F3 and it has 2 inputs which is 2 key keypad which we are using for our application. Now i want to use that keypad for ON/OFF of microcontroller also.How i can do that? I want to ON controller power supply when i press keypad key and then i will use those key for my application also and then if i key for long time or press both keys it will OFF, i.e. power supply cut off. This is like our old keypad mobile phones which has 1 key for Mobile phone ON and that same key we can use for receiving call also. How can i do that for my STM8L051F3?
