I am currently facing an issue with the MCF51JM128 microcontroller in some devices. Specifically, I have observed that when the controller wakes up from sleep mode, it enters an undefined state, causing the controller pins to output a voltage of 3.6V.
Hi,
Could you help to provide more info about this issue with below questions?
What's the operating voltage (VDD) of MCF51JM128?
Which sleep mode the chip enter into?
What's the issued pad/pins output voltage during sleep mode?
What's the wake up source?
Which pad has this issue? Please help to list the pad info.
Thank you.
Mike
