Wake up from Sleep mode or low power mode internally


Is it possible to get into a timed sleep mode with Q2501b.

That means the module goes into sleep by shutting (powering off) almost everything except the rtc. The RTC generates an interrupt after the expiry of the sleep duration.
The module works independently and has no connection with RS232
I have the following command in mind but its not clear they can do what I want.
Any response will be most appreciated.
