NOTES: 14. The latching sequence is initiated by a rising edge on LCLK. For modes in which multiple groups of data
are latched, the LCLK rising edge latches all the groups and the pixel clock shifts them out starting with the
low-numbered group. For example, in pseudo-color submode 3 with a 16-bit pixel-bus width, the rising edge
of LCLK latches all the data groups shown above (s13) and the pixel clock shifts them out in the order
P(3–0), P(7–4), P(11–8), and P(15–12). Note that each line in each subtable above represents one pixel.
15. When in the big-endian format (GCR3 =1), the pixel bus is externally swapped by the user (i.e., D31
connected to P0, D0 connected to P31). Since data is always shifted out from low-numbered groups to
high-numbered groups, the external swapping of the pixel bus causes the groups to be shifted out in the
correct order. However, for modes with more than 1 bit per pixel, the bits in each data group are reversed
(LSB to MSB). This is internally corrected by the VIP input multiplexer. The differences between big- and
little-endian data formats and how they affect the pixel bus operation is discussed in more detail in
Appendix C.
