Address Decoder (DEC)
There are additional memory map registers for fast peripherals, but these are never moved. In addition,
several peripheral register sets, including the System Module, are located at fixed locations in high
memory. All of these memory locations are given in the reference sections for each register.
Figure 16-1 illustrates where memory is mapped at device reset, in ROM Mode, and in Flash Mode:
