    I am working with the MM912F634. I want to entry STOP mode to reduce current consumption, and wake up from L0 input. My code as following:


WCR = 1;                     // Enable the L0 wake-up

asm ADNCC #0x6F;    // Enable the STOP mode

MCR = 1;                     // Set the Analog Die transition to Stop mode.

asm STOP;                  // MCU entry Stop mode.


the program did work after "asm STOP". but after changing the L0 input level, the device always reset , then entry Stop mode again.

     I am appreciate if you could give me some advice.


Best regards,
