1. Re: Periodly wakeup from deep sleep mode
JoMe_264151 Oct 7, 2015 2:01 AM (in response to userc_40693)You can wakeup from DeepSleep mode periodically by using the WDT (WatchDog Timer) and the LFCLK (Low Frequency CLock). When you have got an external signal to wakeup the chip you may connect that to a pin and get woken by an interrupt. There are only few components running in DeepSleep.

3. Re: Periodly wakeup from deep sleep mode
userc_40693 Oct 13, 2015 1:16 AM (in response to userc_40693)How can I close ECO clock in my lowpower mode? Use CysysclkEcoStop() API or disable ECO component in .cysch ? I found CysysClkEcoStop() is useless when I was testing my deep sleep mode current consumption, but disable ECO component in .cysch is useful, it made my current consumption smaller.
Best Regards!

DaKn_263916 Oct 13, 2015 2:00 PM (in response to userc_40693)In AN92584 did you implement the BL:ESS power mode before turning off ECO ?
