5] The sum of all IOH, for ports D3 - D7, should not exceed 100mA.
6] The sum of all IOH, for ports C0 - C7, should not exceed 100mA.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.
CC
for Power-down is 2.5V.
