Figure 5: Overall Timing Diagram for the 1200dpi Mode
Figures 6 and 7 detail the timing of the CLK, GBST, Vout, and SI/SO signals in further detail, which have the same timing requirements
for both the 600 and 1200dpi modes. The rise and fall times are listed in Table 5. In Figure 7, note that pixel 111 is the first active pixel.
