26.2 Memory Configuration

The 128 KB internal flash memory area is divided into 64 blocks and can be programmed/erased in block units. All
the blocks can also be erased at once.
When the boot swap function is used, the physical memory (blocks 0 to 3) located at the addresses of boot area 0
is replaced by the physical memory (blocks 4 to 7) located at the addresses of boot area 1. For details of the boot
swap function, refer to 26.5 Rewriting by Self Programming.
