AT91SAM9261
The memory blocks assigned to SRAM A, SRAM B and SRAM C areas are not contiguous and
when the user dynamically changes the Internal SRAM configuration, the new 16 Kbyte block
organization may affect the previous configuration from a software point of view.
Table 8-5 illustrates different configurations and the related 16 Kbyte blocks (RB0 to RB9)
assignments.
Note:
1. Configuration after reset.
8.1.1.2
Internal ROM
The AT91SAM9261 integrates a 32 Kbyte Internal ROM mapped at address 0x0040 0000. It is
also accessible at address 0x0 after reset and before remap if the BMS is tied high during reset.
8.1.1.3
USB Host Port
The AT91SAM9261 integrates a USB Host Port Open Host Controller Interface (OHCI). The reg-
isters of this interface are directly accessible on the AHB Bus and are mapped like a standard
internal memory at address 0x0050 0000.
8.1.1.4
LCD Controller
The AT91SAM9261 integrates an LCD Controller. The interface is directly accessible on the
AHB Bus and is mapped like a standard internal memory at address 0x0060 0000.
