13.2. Functional description

The SSMC core performs read and write accesses to external memory through the AMBA AHB slave interface. Figure 13.1 shows a block diagram of the SSMC core. Figure 13.2 and Figure 13.3 shows the data and control signal multiplexing.

If the select signal CFGMPMCnSMC is HIGH, the MPMC controller is used in place of the SSMC. The multiplexing circuitry for the static address, data, and control signals is shown in Figure 13.2 and Figure 13.3.
