3.8 GPIO Modes
There are two supported GPIO modes:
• Disabled (default)
• VSYNC enabled
In disabled mode, no signals are provided as input or output on the GPIO pins. In VSYNC mode, a video sync
signal is provided as an output on GPIO3. The purpose of this signal is more fully described in Frame
Synchronization, page 53.
NOTE: GPIO0, GPIO1, and GPIO2 should not be connected, regardless of the
selected GPIO mode.
