6.5 Hardware cursor
Table 251. Palette data storage for STN color modes.
For monochrome STN mode, only the red palette field bits [4:1] are used. However, in
STN color mode the green and blue [4:1] are also used. Only 4 bits per color are used,
because the gray scaler only supports 16 different shades per color.

mode.
Table 252. Palette data storage for STN monochrome mode.
The hardware cursor is an integral part of the LCD controller. It uses the LCD timing
module to provide an indication of the current scan position coordinate, and intercepts the
pixel stream between the palette logic and the gray scale/output multiplexer.
All cursor programming registers are accessed through the LCD slave interface. This also
provides a read/write port to the cursor image RAM.
The hardware cursor is contained in a dual port RAM. It is programmed by software
through the AHB slave interface. The AHB slave interface also provides access to the
hardware cursor control registers. These registers enable you to modify the cursor
position and perform various other functions.
When enabled, the hardware cursor uses the horizontal and vertical synchronization
signals, along with a pixel clock enable and various display parameters to calculate the
current scan coordinate.
