5.1.7.1.3. Non Funtional Requirements
| The system should allow the pins to react to changes between high and low in no more than 10 microseconds. | 
| The system should respond in 1 microsecond when setting a pin. | 
| The system should allow input pins for reading signals to check inputs at least 10000 times per second. | 
| The system should make the pins consume less than 1 microampere when in low power mode. | 
| The pins should not exceed 1 milliampere of power when in use. | 
| The pins should be able to switch on and off at least 10 million times. | 
| The pins should work well at temperatures between -40°C to +85°C. | 
| The GPIO pins should be able to handle signals of up to 5V. | 
| The GPIO pins must go into low-power mode when not in use. |
