Hello Folks,

   

 

   

I'm putting PSoC5LP in sleep mode as soon as it receives an int coming from the LV detection block (raised thru the Global Signal component). There's of course a battery back up feeding the CPU while the PS is off, mainly for ram retention & keeping the RTC running.

   

However when the power supply comes back to life, I'm unable to wake up the processor using  CyPmSleep(PM_SLEEP_TIME_NONE, PM_SLEEP_SRC_VD).

   

There is not so much doc/explanation/example about PM_SLEEP_SRC_VD used whithin CyPmSleep.

   

Is anyone able to give me further explanation?

   

Michel
