4.4 SRAM Programming Model
The SRAM programming model consists of RAMBAR.
4.4.1 SRAM Base Address Register (RAMBAR)
The SRAM modules are configured through the RAMBAR, shown in Figure 4-1.

Name
Base address. Defines the SRAM module’s word-aligned base address. The SRAM module
occupies a 4-Kbyte space defined by the contents of BA. SRAM may reside on any 32-Kbyte
boundary in the 4-Gbyte address space.
Reserved, should be cleared.
Write protect. Controls read/write properties of the SRAM.
0 Allows read and write accesses to the SRAM module
1 Allows only read accesses to the SRAM module. Any attempted write reference generates an
Reserved, should be cleared.
