conditions (non-transient), the following must be observed:
1.)The sum of all IOL, for ports A0-A7, G2, C4-C7 should not exceed 100 mA.
2.)The sum of all IOL, for ports C0-C3, G0-G1, D0-D7 should not exceed 100 mA.
3.)The sum of all IOL, for ports G3-G5, B0-B7, E0-E7 should not exceed 100 mA.
4.)The sum of all IOL, for ports F0-F7 should not exceed 100 mA.
If IOL exceeds the test condition, VOL may exceed the related specification. Pins are not guaranteed to sink current greater
than the listed test condition.
state conditions (non-transient), the following must be observed:
1)The sum of all IOH, for ports A0-A7, G2, C4-C7 should not exceed 100 mA.
2)The sum of all IOH, for ports C0-C3, G0-G1, D0-D7 should not exceed 100 mA.
3)The sum of all IOH, for ports G3-G5, B0-B7, E0-E7 should not exceed 100 mA.
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.
