There is also a single combined interrupt that is asserted when any of the individual
interrupts become active.
Figure 12–36
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 only access the 10 kB SRAM on AHB1 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.
