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.
Figure 8.1 SRAM mapping
Where internal memory overlays external memory, internal memory is accessed in preference.
