4)The sum of all IOH, for ports F0-F7 should not exceed 100 mA.

If IOH exceeds the test condition, VOH may exceed the related specification. Pins are not guaranteed to source current

greater than the listed test condition.

5. Values indicated represent typical data from design simulation.

Notes:

1. All bits set in the “PRR – Power Reduction Register” on page 47.
