INTRODUCTION
The MPLAB XC32 C/C++ Compiler supports a number of special features and exten-
sions to the C/C++ language which are designed to ease the task of producing
ROM-based applications. This chapter documents the special language features which
are specific to these devices.

DEVICE SUPPORT
MPLAB XC32 C/C++ Compiler aims to support all PIC32 devices. However, new
devices in these families are frequently released. Check the readme document for a full
list of all available devices.

DEVICE HEADER FILES
There is one header file that is recommended be included into each source file you
write. The file is <xc.h> and is a generic file that will include other device-specific
header files when you build your project.

Inclusion of this file will allow access to SFRs via special variables, as well as

s which allow the use of conventional register names from within assembly
language files.

CP0 Register Definitions Header File
The CP0 register definitions header file (cp0defs.h) is a file that contains definitions
for the CP0 registers and their fields. In addition, it contains macros for accessing the
CP0 registers.
