4.4 SRAM Programming Model
The SRAM programming model consists of RAMBAR0 and RAMBAR1.
4.4.1 SRAM Base Address Registers (RAMBAR0/RAMBAR1)
The SRAM modules are configured through the RAMBARs, shown in Figure 4-1.

• Each RAMBAR holds the base address of the SRAM. The MOVEC instruction
• Each RAMBAR can be read or written from the debug module in a similar manner.
• All undefined RAMBAR bits are reserved. These bits are ignored during writes to
• The valid bits, RAMBARn[V], are cleared at reset, disabling the SRAM modules.

Name
Base address. Defines the SRAM module’s word-aligned base address. Each SRAM module
occupies a 2-Kbyte space defined by the contents of BA. SRAM may reside on any 2-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
Data/instruction bus. Indicates whether SRAM is connected to the internal data or instruction bus.
0 Data bus
1 Instruction bus
