I'm developing an ATTiny85 project. 9VDC is fed to the board where it gets regulated down to 5V. My test program just outputs a square wave on all 6 IO pins. Everything looks fine (i.e. low = 0, hi = 5V) with the emulator unplugged, but when I plug it into the ISP connector on the board the outputs drop to lo = 0, hi = 3V. This only happens when I'm in debug mode, though debugging works fine. Any idea why? Thanks.
