4.5.14.1 CS5530 Video Port Data Transfer
VID_VAL indicates that the GX1 processor has placed valid
data on VID_DATA[7:0]. VID_RDY indicates that the
CS5530 is ready to accept the next byte of video data.
VID_DATA[7:0] is advanced when both VID_VAL and
VID_RDY are asserted. VID_RDY is driven one clock early
to the GX1 processor while VID_VAL is driven coincident
with VID_DATA[7:0]. A sample interface functional timing
diagram is shown in Figure 4-17.
