Tool/software:
Hi,
Is the RTC disabled when device enters shutdown mode? After referring the CC2745R10 TRM, I found the below info:
1. RTC is reset when the chip enters reset state and Shutdown state.
2. RTC value is synced with systim after exiting a reset state.
Let's say at 10:00 AM, I put the device into shutdown mode via software and after two hours i.e at 12:00 Pm. I wake the device up via a GPIO configured as wakeup src.
What will the state of the RTC be? Will it have an incremented value or will it be reset as suggested in the first image.
The Power_shutdown API has a "shutdownTime" parameter which can be used to schedule a wakeup from shutdown state. How is this done? Does it use RTC or some other peripheral?
We are trying to optimize the sleep currents and keeping the RTC functionality intact during shutdown is very important for our use case.
