status and the BMS state at reset.
The AT91SAM9G10 embeds a high-speed 16-Kbyte SRAM.
The AT91SAM9G10 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.
The AT91SAM9G10 integrates a USB Host Port Open Host Controller Interface (OHCI). The
registers of this interface are directly accessible on the AHB Bus and are mapped like a standard
internal memory at address 0x0050 0000.
The AT91SAM9G10 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.
The system always boots at address 0x0. To ensure a maximum number of possibilities for boot,
the memory layout can be configured with two parameters.
REMAP allows the user to lay out the first internal SRAM bank to 0x0 to ease development. This
is done by software once the system has booted for each Master of the Bus Matrix. Refer to the
Bus Matrix Section for more details.
When REMAP = 0, BMS allows the user to lay out to 0x0, at his convenience, the ROM or an
external memory. This is done via hardware at reset.
Note:
The AT91SAM9G10 Bus Matrix manages a boot memory that depends on the level on the BMS
pin at reset. The internal memory area mapped between address 0x0 and 0x000F FFFF is
reserved for this purpose.
If BMS is detected at 1, the boot memory is the embedded ROM.
If BMS is detected at 0, the boot memory is the memory connected on the Chip Select 0 of the
External Bus Interface.
Memory blocks not affected by these parameters can always be seen at their specified base
addresses. See the complete memory map presented in
