Section 3.2.3.16 for more information on the ACE controls for the primary input channel.
2.2.2.6. Secondary Input Channel
The ADV8003 secondary input channel incorporates an input formatter, CSC and updither block.
The input formatter provides a number of controls to configure what data the secondary input channel is configured for. The secondary
input channel must be connected to either the video TTL input pins or the EXOSD TTL input pins using
s_inp_chan_sel[1:0]. If the
secondary input channel is connected to the video TTL input pins, the format and bit width of the data, for example, 2 x 8 bit buses of
4:2:2 data, must be specified using
exosd_format_sel[4:0] . exosd_swap_bus_ctrl[2:0] can be used to indicate which input pins are used to
carry the upper, middle and lower ranges of bits (for example, upper = D[35:25], middle = D[24:12], lower = D[11:0]; or upper = D[11:0],
middle = D[35:25], lower = D[24:12]).
