Dear Freescale Community,
When I program my MC9S08PA16 using “standalone flash mode”, and then power up at 3.3V, the MCU will reset when waking from a STOP instruction. This does not happen above 3.4V or below 3.2V, nor does it happen at any voltage in debug mode.
In my design, the MCU wakes from a STOP instruction using either an IRQ interrupt, an RTC interrupt, or a Keyboard interrupt. All show the same issue. I've ensured that the STOPE is set, enabling the STOP functionality. And when I print the reset message I receive an “illegal address” message.
Any thoughts? Thank you for your help.
