Sleep with PWM

Sleep with PWM

When you call CyPmSleep(), are components supposed to shutoff, or just the processor? When I call this function, my PWM modules turn off until I programmatically turn them on.

Follow the steps properly while using Sleep:

1. Put all the components into Sleep (except the components which are sources of wakeup) by calling <Component Name>_Sleep()

2. Save the clock settings by calling CyPmSaveClocks()

3. Put the device into sleep with appropriate wakeup source by calling CyPmSleep(<time>,<source>)

4. After wakeup, restore the clock settings by calling CyPmRestoreClocks()

5. After that, wakeup all your components by calling <Component Name>_WakeUp()
