Macros
The C251 standard library includes definitions for for a number of macros you can use in your programs.
These macros are defined in ABSACC.H and allow you to access the different memory spaces of the 251 hardware.
The absolute memory access macros do not reserve memory at link/locate time. If you want to reserve memory for an object, you must use the _at_ keyword described in Absolute Variable Location.
The function and usage of the absolute memory access macros are explained in the following topics.
