Input signals UD0 through UD3 contain the video data for the upper screen 
and signals LD0 through LD3 contain the data for the lower screen. For 
example, four pixels (UD3:1,1–UD0:1,1) are sent to row 1 at the same time as 
four pixels (LD0:1,1–LD3:1,1) are sent to row 241. This results in eight pixels 
sent on each cycle of video clock CP2. Pixel information is supplied from left to 
right and from top to bottom. Video data for one row is latched on the fall of 
CP1 (Figure 5).
