2.2 Introduction
The memory map, shown in Figure 2-1, includes:
•
•
•
•
2031 bytes of user FLASH memory
128 bytes of random-access memory (RAM)
14 bytes of user-defined vectors in FLASH memory
768 bytes of monitor read-only memory (ROM)
These definitions apply to the memory map representation of reserved
and unimplemented locations:
•
•
Reserved — Accessing a reserved location can have
unpredictable effects on MCU operation.
Unimplemented — Accessing an unimplemented location causes
an illegal address reset.
