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. |
