Screen–split Display Function
The HD66787 allows selectively driving two screens at arbitrary positions with the screen-drive position
registers (R42 and R43). Only the raster-rows required to display two screens at arbitrary positions are
selectively driven to reduce power consumption.
The first screen drive position register (R42) specifies the start line (SS17-10) and the end line (SE17-10)
for displaying the first screen. The second screen drive position register (R43) specifies the start line
(SS27-20) and the end line (SE27-20) for displaying the second screen. The second screen control is
effective when the SPT bit is set to 1. The total number of raster-rows driven for displaying the first and
second screens must be less than the number of liquid crystal drive raster-rows.
