GPS Receiver A1030-A
7 Memory Map
Beside the internal register, RAM and Flash access, the module offers – depending
on its version) additional external Flash and / or SRAM. The external memory is
addressed via a 16bit interface at the following addresses:
Memory type Address
Flash 0x60000000
SRAM
0x62000000
Table 8: External memory map
A theoretical total of a memory space of 2
24
bytes (corresponding to 16 Mbytes or
128 Mbit) of SRAM and Flash respectively can be addressed. Not existing memory
is simply mirrored. For example the Flash memory of a module equipped with 8Mbit
will be seen at address 0x60000000, 0x60100000, 0x60200000, and so on.
