3 MEMORY MAPS, PROGRAMMING MODES AND OPTION BYTES

3.1 MEMORY AND REGISTER MAPS

3.1.1 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 OTP and user vectors; Data space con-

tains user data in RAM and in OTP, and Stack

space accommodates six levels of stack for sub-

routine and interrupt service routine nesting.
