Unpredictable Behavior if BOD is Disabled, VDDCORE is Lost and VDDIO is Connected
In active mode or in wait mode, if the Brownout Detector is disabled (SUPC_MR: BODDIS=1) and power is lost on
VDDCORE while VDDIO is powered, the device might not be properly reset and may behave unpredictably.
Problem Fix/Workaround
When the Brownout Detector is disabled in active or in wait mode, VDDCORE always needs to be powered.
