Shown below is an example of the implementation on the AT91SAM9G20-EK Rev.C.
VDDCORE and VDDBU are controlled by Power-on-Reset (POR) to gurantee that these power
sources reach their target values prior to the release of POR. (See
• VDDIOM and VDDIOP must NOT be powered until VDDCORE has reached a level superior
• VDDIOM and VDDIOP must be ≥ 0.7V within (T2 + T3) after VDDCORE reaches
