AHB
The LCD controller includes two separate AHB interfaces. The first, an AHB slave
interface, is used primarily by the CPU to access control and data registers within the LCD
controller. The second, an AHB master interface, is used by the LCD controller for DMA
access to display data stored in memory elsewhere in the system. The LCD DMA
controller can access any SRAM on AHB and the external memory.
The AHB slave interface connects the LCD controller to the AHB bus and provides CPU
accesses to the registers and palette RAM.
The AHB master interface transfers display data from a selected slave (memory) to the
LCD controller DMA FIFOs. It can be configured to obtain data from any on-chip SRAM on
AHB, various types of off-chip static memory, or off-chip SDRAM.
