+title: HDMI CEC GPIO

+description: |
+  The HDMI CEC GPIO module supports CEC implementations where the CEC line is
+  hooked up to a pull-up GPIO line and - optionally - the HPD line is hooked up
+  to another GPIO line.
+
+  Please note:: the maximum voltage for the CEC line is 3.63V, for the HPD and
+  5V lines it is 5.3V. So you may need some sort of level conversion
+  circuitry when connecting them to a GPIO line.

+      GPIO that the HPD line is connected to.  Used for debugging HPD changes
+      when the CEC line is not associated with an HDMI receiver/transmitter.
