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 10.
9.1
There is an internal memory module of 64 Kbytes of SRAM. The internal SRAM is mapped into the
base of the memory space from MinInt (#80000000) extending upwards.
This memory can be used to store on-chip data, stack or code for time critical routines.
Optional external RAM, if fitted, is addressed from #81000000.
9.2
There is 128 Kbytes of on-chip ROM for application code.
