I am using a Colfire MCF52259 processor with a 3.3V battery connected to the Vstby pin.
With the battery connected (and circuit powered), I am unable to 'flash' program the proccesor using a P&E Micro BDM.
If I remove the battery, the device programs without any issue.
I have also noticed the processor will not start-up if the standby battery voltage is slightly high (3.6V).
Is this 'normal' operation for these devices?
