K24 rtc_clkout in low power mode ?

Hello,

 

I am using a 32 khz crystal connected to extal32 and xtal32 and running the output to the rtc_clkout pin.

What is the lowest power mode that this function will work ?

 

The reason I ask is the reference manual says rtc_clkout is disabled in LLS and VLLS2 modes suggesting

VLPS is the lowest power mode at a typical of 57 uA.

 

The problem we see is that this function is still working in VLLS2 mode. Is the manual wrong ?

 

If not, why is it still working ?

 

Regards,

 

Dennis
