Configuration Block
Datapath
Note:
This block has the same functionality as Channel-U, but for the Lower Panel in dual scan mode
only.
This block receives the request signals from the LCDC core and generates the requests for the
channels.
The configuration block is a set of programmable registers that are used to configure the LCDC
core operation. These registers are written via the AHB slave interface. Only word access is
allowed.
The description of the configuration registers can be found in
Interface” on page
The datapath block contains five submodules: FIFO, Serializer, Palette, Dithering and Shifter.
The structure of the datapath is shown in
• LINESIZE is the horizontal size of the display in pixels, minus 1, as programmed in the
• Bpp is the number of bits per pixel configured.
• PIXELOFF is the pixel offset for 2D addressing, as programmed in the DMA2DCFG register.
• LINEVAL is the vertical size of the display in pixels, minus 1, as programmed in the LINEVAL

field of the LCDFRMCFG register of the LCD Controller.
X_size is calculated as an up-rounding of a division by 32. (This can also be done adding 31 to the
dividend before using an integer division by 32). When using the 2D-addressing mode (see
Memory Addressing” on page
cuted and the FRMSIZE field programmed with every movement of the displaying window, since a
change in the PIXELOFF field can change the resulting FRMSIZE value.
