Single signal software selectable between display enable and Blank#.5.5.1 Analog Display Port CharacteristicsThe analog display port provides a RGB signal output along with a HSYNC and VSYNC signal.There is an associated DDC signal pair that is implemented using GPIO pins dedicated to theanalog port. The intended target device is for a CRT-based monitor with a VGA connector. Displaydevices (e.g., LCD panels with analog inputs) may work satisfactory but no functionality has beenadded to the signals to enhance that capability.Table 33.
