BRSTLN field of the DMAFRMCFG register. For details on this register, see

This block stores the base address and the number of words transferred for this channel (frame
in single scan mode and Upper Panel in dual scan mode) since the beginning of the frame. It
also generates the end of frame signal.
It has two pointers, the base address and the number of words to transfer. When the module
receives a new_frame signal, it reloads the number of words to transfer pointer with the size of
the frame/panel. When the module receives the new_frame signal, it also reloads the base
address with the base address programmed by the host.
The size of the frame/panel can be programmed in the FRMSIZE field of the DMAFRMCFG
Register. This size is calculated as follows:
where:
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.
