Configuration Block
Datapath
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
This module transforms the data read from the memory into a format according to the LCD mod-
ule used. It has four different interfaces: the input interface, the output interface, the
configuration interface and the control interface.
• The input interface connects the datapath with the DMA controller. It is a dual FIFO interface
with a data bus and two push lines that are used by the DMA controller to fill the FIFOs.
