I once had a situation where I did not get a predictable POR because of the various paths from connected pins. Of course, you can't always avoid all of those. ----- Original Message ----- From: "John Samperi" <samperi@ampertronics.com.au> To: AVR-Chat@yahoogroups.com Sent: Friday, August 24, 2012 2:27:17 PM Subject: RE: [AVR-Chat] voltage on an AVR pin when powered off At 12:32 AM 25/08/2012, you wrote: >So, what if GND as well as Vcc to the chip are both turned off, ..and what about the rest of the pins? Draw a box with as many I/O pins as the chip you are using has. Then draw 2 diodes, one to the ground pin and one to the VCC pin just like they show in the datasheet. Then you can follow the current paths in and out of the chip. Regards John Samperi ******************************************************** Ampertronics Pty.
