The above configuration can be changed frame to frame, so the displayed window can be
moved rapidly. Note that the FRMSIZE field of DMAFRMCFG register must be updated with any
movement of the displaying window. Note also that the software must write bit DMAUPDT in
DMACON register after each configuration for it to be accepted by LCDC.
Note:
• Define the width of the complete frame buffer by programming in the field ADDRINC of
• Enable the 2D addressing mode by writing the DMA2DEN bit in DMACON register. If this bit
DMA2DCFG register the address increment between the last word of a line and the first word
of the next line (in number of 32-bit words).
is not activated, the values in the DMA2DCFG register are not considered and the controller
assumes that the displayed area occupies a continuous portion of the memory.
In 24 bpp packed mode, the DMA base address must point to a word containing a complete pixel
(possible values of PIXELOFF are 0 and 8). This means that the horizontal origin of the displaying
window must be a multiple of 4 pixels or a multiple of 4 pixels minus 1 (x = 4n or x = 4n-1, valid ori-
gins are pixel 0,3,4,7,8,11,12, etc.).
