8.2 Flash - Non-volatile memory
The Flash can be read an unlimited number of times by the CPU, but it has restrictions on the number of
times it can be written and erased and also on how it can be written.
Writing to Flash is managed by the Non-volatile memory controller (NVMC), see NVMC Non-volatile
memory controller on page 29.
The Flash is divided into multiple pages that can be accessed by the CPU via both the ICODE and DCODE
buses as shown in, Figure 4: Memory layout on page 23. Each page is divided into 8 blocks.
8.3 Memory map
The complete memory map is shown in Figure 5: Memory map on page 24. As described in Memory on
page 23, Code RAM and the Data RAM are the same physical RAM.
