4.3.2. System memory map

The decoder controls the memory map of the system, and generates a slave select signal for each memory region.

The Remap signal is used to provide a different memory map at reset, when ROM is required at address 0x00000000, and during normal operation, when internal RAM can be used at address 0x00000000.

The Remap signal is typically provided by a remap and pause peripheral, which drives Remap LOW at reset. The signal is driven HIGH only after a particular address in the remap and pause peripheral is accessed.

Figure 4.13 shows both the normal and reset memory maps.
