Hello folks, I want to use one of the GPIOs on 2541 (maybe interrupts too) to switch on/off another chip via a FET. I need to be absolutely sure that the GPIO is hard grounded, therefore gives 0uA (low) while sleeping.
I'm looking at 10+ years of battery life, so this is very important to me. Can someone give me any information on this subject? Thanks in advance!
Harry
