HDMI Video Processor Interface
The
Figure 41
shows the connections between the processor and the HDMI framer
device. There are 16 bits of display data, 5-6-5 that is used to drive the framer. The
reason for 16 bits is that allows for compatibility with display and LCD capes already
available on the original BeagleBone. The unused bits on the TDA19988 are tied low. In
addition to the data signals are the VSYNC, HSYNC, DE, and PCLK signals that round
out the video interface from the processor.
