I am using 12F675, I checked before programming that the clock was running and the chip drew only the normal microamps. After programming, the chip drags down my 3 amp power supply and gets very hot. Erasing the program does not help. How does one program a 12F675 to be a short circuit? My programmer is melabs U2. Has it failed again (this is my second one)? My test circuit is just power and ground and pin 4 (reset) grounded.
