Memory Spaces
There are four memory spaces that the bootloader can access and program:
• Program Memory (0x0800-0x7FFF)
• User ID Memory (0x200000-0x200007)
• EEPROM Memory (0x0F0000-0x0F00FF)
• Configuration Memory (0x300000-0x30000D)
The bootload also reads and displays the read-only Device ID Words at 0x3FFFFE
and 0x3FFFFF.
FIGURE 3-4:
Note:
The data EEPROM is actually located in a different memory space than
shown here. The address range given is remapped by the bootloader to the
proper memory when data EEPROM access is required.
