What makes it harder on other processors? They all have to do the same stuff, switch to an internal clock, shut off the high speed clock to save power, stop the processor pending an interrupt, on wakeup the high speed clock has to be restarted and then switched to once stable then the processing resumed. The problem with this is usually the time it takes for the oscillator to restart. Everything is eating power with no work being done while waiting, so loss of efficiency. If your rate of power mode switching is high, it eats into your savings severely. Can you share some insight into what makes the MSP430 power schemes easier to use? -- Rick
