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.
