1.3 MEMORY MAP

1.3.1 Introduction

The MCU operates in three separate memory

spaces: Program space, Data space, and Stack

space. Operation in these three memory spaces is

described in the following paragraphs.

Briefly, Program space contains user program

code in Program memory and user vectors; Data

space contains user data in RAM and in Program

memory, and Stack space accommodates six lev-

els of stack for subroutine and interrupt service

routine nesting.
