In synchronous parallel interface configuration, the required data is provided by the DISPC TV output, and control signals are provided by the HDMI module. Then they are merged and provided to the DPI1 output.
This configuration option is available and can be selected through the DSS_CTRL[17:16] PARALLEL_SEL bit field (multiplexer 13 in Figure 13-4).
Table 13-4 lists the outgoing display subsystem signals on the device boundary pads.
