Figure 11.2 shows a block diagram of the DMABRG.
For data transfer in DMABRG mode between synchronous DRAM and the LCDC, HAC, SSI, or
USB, the DMABRG performs a high-speed data transfer via the DMABRG internal FIFO (32-bit
16-stage) using DMAC channel 0. The DMABRG transfers a maximum of 32-byte data in a single
transfer.
