32-Bit-Wide Memory Interface

Case 3: 32-Bit-Wide Memory With 32-Bit Data-Type Size

When the data size is 32 bits, the ’C32 does not shift the internal address

before presenting it to the external address pins. In this case, the memory

interface copies the value of the internal address bus to the respective external-

address pins. Also, the memory interface activates STRBx_B3

STRBx_B0 pins during accesses. Figure 10–13 shows a functional diagram

of the memory interface for 32-bit-wide memory with 32-bit data size.
