Although each I/O port can sink or source more than the test conditions under steady state conditions (non-transient), the following must be observed:

1.The sum of all IOL, for GPIO4-GPIO7 should not exceed 100 mA.

2.The sum of all IOL, for GPIO0-GPIO3, GPIO8-GPIO15 should not exceed 100 mA.

3.The sum of all IOL, for GPIO24-GPIO31 should not exceed 100 mA.

4.The sum of all IOL, for GPIO16-GPIO23 should not exceed 100 mA.

5.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.

6.The sum of all IOH, for GPIO4-GPIO7 should not exceed 100 mA.

7.The sum of all IOH, for GPIO0-GPIO3, GPIO8-GPIO15 should not exceed 100 mA.

8.The sum of all IOH, for GPIO24-GPIO31 should not exceed 100 mA.

9.The sum of all IOH, for GPIO16-GPIO23 should not exceed 100 mA.
