Thanks a lot Brian!
By frozen, did u mean that the port pins retain their values ?
And some of the features in the controller like A/D converter and comparator functions in the sleep mode. What will be the status of clock in these cases ?
And i got your point on the triggering by external interrupt to wake the processor up, but how does the watch dog timer do that ? Does it have a separate clock running ?
And when it come to practical applications, how much power can the controller actually with being in the sleep mode with all the peripherals and pins turned off ?
Sorry for all these basic stupid questions, but i m actually trying to get a deeper understanding of the sleep mode and have to use an ultra power sleep mode.
Any reference or any kind of materials would be of great help!!
Thanks again!
