Data Memory Structure

General Purpose Data Memory

All microcontroller programs require an area of read/write memory where temporary data can be 
stored and retrieved for use later. It is this area of RAM memory that is known as General Purpose 
Data Memory. This area of Data Memory is fully accessible by the user programing for both reading 
and writing operations. By using the “SET [m].i” and “CLR [m].i” instructions individual bits can 
be set or reset under program control giving the user a large range of flexibility for bit manipulation 
in the Data Memory. 

Special Purpose Data Memory

This  area  of  Data  Memory  is  where  registers,  necessary  for  the  correct  operation  of  the 
microcontroller, are stored. Most of the registers are both readable and writeable but some are 
protected and are readable only, the details of which are located under the relevant Special Function 
Register section. Note that for locations that are unused, any read instruction to these addresses will 
return the value “00H”.
