Low Power Modes
I'm testing the low power modes of Psoc3:
- On one hand, I've read on AN66083 that when the device is in Sleep mode, "all subsystems except supervisory modules such as CTW and WDT (if enabled) are disabled".
- On the other hand, in the head "Switching to Sleep Mode" advices that, before you call the Sleep function(CyPmSleep()), you've to call the Sleep Component routines (Component_Sleep()).
I've tried a Creator Project which uses a Comparator in order to make a LED light up. I haven't used the function Comparator_Sleep() and, when the device goes to Sleep mode, the Comparators still working. Why the Comparator works despite the device is in Sleep Mode? Is it actually the device in Sleep mode or do you have to use the Component Sleep function?
