| By default, the micro:bit display driver will update the GPIO |
| pins of the display (pins 4 through 15) by accessing the entire |
| GPIO port. This is done for efficiency, however it may interfere |
| with other peripherals connected to the same GPIO port. Select |
| this option if other peripherals are connected to the same GPIO |
| port. |
