Status of HFCLK after shutting down the radio

[Abdelraouf Ouadjaout]

Hi,

I would like to save the most energy when going to sleep mode. In particular, I want to turn off all modules except the RTC timer.

So, after shutting down the radio, and before executing WFI, do I have to shut down HFCLK also by calling HFCLKSTOP task? Or is it automatically turned off by the MCU when no subsystem is using it?

Thanks in advance.
