Problem with ATmega32A reset function when power down.
Hi,
I am new to microcontroller programming, I am confusing with reset function. I have one external Reset circuit (using 220nf capacitor and 56k resistor in parallel) to Reset microcontroller which is working good.
When power-off and power-on the microcontroller is not functioning. When i press external reset button then it is working. I didn't understand what might be the problem why it is not starting automatically when power on? I need to press external reset button always when i lose power.
I checked the fuse bits and it seems everything ok.
I want to know do i need to write any code for this to run the microcontroller when power-on? do i need to set any registers?
Please can anyone help me with this.
