    you 'can' do a software reset, BUT it is not THAT easy. Just jumping to zero does not do it. All SFRS have 'startup values' you need to restore all those before jumping to zero. Also, if you try it from inside an ISR it gets even more complicated since you need to restore some registers not 'publically available'

    Thus

    FORGET ABOUT A SOFTWARE RESET, just let the watchdog time out.
