LC60: RTI is not working in FEI mode at stop3 but it is in FEE?

[BasePointer]

Hi,

I'm using external 32.768 crystal for RTC functionality. My main routine is actualy using FEE mode. If I want to switch active clock mode from FEE to FEI or SCM before entering stop3, the RTI is also stopping and MCU is not waking in stop3 via RTI. If I leave it on FEE mode, RTI is working also in stop3 mode.

But in normal RUN MODE, RTI is always works properly.

Is this a normal behaviour?

Thank you,

BP.

Himm, yes unfortunately it seems normal behaviour.

Code:

OSCSTEN: Enable Oscillator in Off Mode — The OSCSTEN bit controls whether or not the oscillator circuit remainsenabled when the ICG enters off mode. This bit has no effect if HGO = 1 and RANGE = 1.0 Oscillator disabled when ICG is in off mode unless ENABLE is high, CLKS = 10, and REFST = 1.1 Oscillator enabled when ICG is in off mode, CLKS = 1X and REFST = 1

 
I set this bit to enable oscillator when ICG is in off mode. But it is only valid when CLKS = 1X that means FEE or FBE

10x,

BP.
