Hi Everyone,
I am about to implement deep sleep management in my application on TM4C129. I am registering 3 or 4 interrupt routines to come out of deep sleep and i configured the clock at 32KHZ using RTC clock of hibernate module during deep sleep. My processor is configured at 120MHZ in run mode.
I got some doubts during implementation:
1) When i exit from deep sleep due to any of the registered interrupts, do i need to change the clock to 120MHZ or is it taken care automatically?
2) Is there a way to calculate the time to wake-up from deep sleep?
3) Is it possible to stop at WFI instruction during deep sleep exit, so that i can wait until the clock changed to 120MHZ and then service ISR? If possible is there any sample framework to do it?
Regards,
Suresh
