+ * . Another passthrough but I haven't spent any time investigating it.
+ * . Digital I/O (logic level connected to GPIO) is available from an
+ * onboard header.
+ *
+ * The on chip input mux should always be set to 2.
+ * GPIO[16:19] - Video input selection
+ * GPIO[0:3] - Video output monitor select (only available from one 878A)
+ * GPIO[?:?] - Digital I/O.
+ *
