Can DA14580 wake up from Extended or Deep sleep by Timeout?

Does DA14580 have "sleep timer"(using 32kHz Clock) to wake up from extended/deep sleep?

For example,I want to implement these flow.
 1.Timer is started( Timeout: 3 second)
 2.DA14580 goes extended sleep,
 3.After 3 second is passed, Wake up interrupt is occurred.
 4.DA14580 starts advertising.

Best regards.

"BLE_DEEPSLWKUP_REG" is not available ?

This register's description is written as /* Time (measured in Low Power clock cycles) in Deep Sleep Mode before waking-up the device */ in DA14580_SDK_v_2.0.4.
But, BLE_DEEPSLWKUP_REG is not used..
Does Dialog prepare application note for "BLE_DEEPSLWKUP_REG"?

Hi Joichi,

These registers are not suppost to be altered by the application code but rather by the provided drivers in the SDK. For instance for the sleep time, the advertisement interval time and connection interval time is use as base.
I hope this explains the usage.
