I'm working on an ATMega6450 design where I'll be using all the IO pins. Programming and debug are via JTAG, but I also need these pins for output. They'll be driving coils that can't be on for more than 1 ms in a 20% duty cycle or they'll overheat. Will this be an issue, or will JTAG holding the chip in reset during programming keep everything low? Will I be OK during debug, as long as I don't break with any of the coils energized? Anything else I should be thinking about? Thanks.
