User manual
4.1 Programmable parameters
4.2 Hardware cursor support
The following key display and controller parameters can be programmed:
The hardware cursor feature reduces software overhead associated with maintaining a
cursor image in the LCD frame buffer.
Without this feature, software needed to:
In addition, the LCD driver had to check whether the graphics operation had overwritten
the cursor, and correct it. With a cursor size of 64x64 and 24-bit color, each cursor move
involved reading and writing approximately 75KB of data.
