I have built the following circuit to reset an AtTiny1614 (the mega tiny 1 series). They don't have a reset switch and I thought with this circuit I could (hard-)reset the chip by doing a power cycle.
I've built the circuit (with the help of cheap Chinese pcb manufacture) and I measure around 1.7-3.6v between VDD and GND while pressing the button.
- Is the ATtiny receiving some kind of "parasitic" ground (sorry, I don't know the correct expression) from other pins that are pulled to ground?
- Would the schematic work, if I would switch the misfet to a p-channel and use it on VDD? Or would there be some kind of "parasitic" 5V?
- Any other suggestion on how I can power cycle the chip?
