Our customer has a problem that SACKERR (Stop Mode Acknowledge Error Reset) occur after executing an WFI instruction.
According to the reference manual (K10P144M100SF2V2RM, Rev 2), this reset is generated if the core attempts to enter stop mode, but not all modules acknowledge stop mode within 1025 cycles of the 1 kHz LPO clock.

But they cannot find out detail information about why modules does not acknowledge stop mode.
Please send detail information and check list for the SACKERR reset as soon as possible.


Best regards,
