3.5.5 How Does the Compiler Place Everything in Memory?

In most situations, assembly instructions and directives associated with both code and data are grouped into sections, and these are then positioned into containers which represent the device memory. To see what sections objects are placed in, use the option -ai to view this information in the assembler listing file.

The exception is for absolute variables, which are placed at a specific address when they are defined and which are not placed in a section. For setting absolute variables, use the address() attribute specified under 8.11 Variable Attributes.
