8 Memory subsystem

The memory system consists of SRAM and a programmable memory interface. The specific details

on the operation of the memory interface are described separately in Chapter 9.

8.1 SRAM

There is an internal memory module of 4 Kbytes of SRAM. The internal SRAM is mapped into the

base of the memory space from MinInt (#80000000) extending upwards, as shown in Figure 8.1.

This memory can be used to store on-chip data, stack or code for time critical routines.
