Chapter 4. Low Level Processor Control
This chapter discusses access to the low level registers and configuration of the
PIC32MX devices.
Items discussed in this chapter are:
• Generic Processor Header File
• Processor Support Header Files
• Peripheral Library Functions
• Special Function Register Access
• CP0 Register Access
• Configuration Bit Access
The generic processor header file is a C file that includes the correct processor-specific
header file based on the processor specified with the -mprocessor command line
option. The generic processor header file is located in
c:\Program Files\Microchip\MPLAB C32\pic32mx\include, where
c:\Program Files\Microchip\MPLAB C32 is the directory in which the MPLAB
C32 toolchain was installed. Besides including the correct processor-specific header
file, the generic processor header file also provides #defines which allow the use of
conventional register names from within assembly language files.
To include the generic processor header file, use the following from within your source
code:
#include <p32xxxx.h>
Inclusion of the generic processor header file allows your source code to be compiled
for any of the processors supported by the MPLAB C32 toolchain without having to
change the file which is being included.
The processor-specific header files are files that contain external declarations for the
Special Function Registers (SFRs) for use in either C or assembly. By convention, each
SFR is named using the same name that appears in the data sheet – for example,
WDTCON for the watchdog timer control register. If the register has individual bits that
may be of interest, there is also be a structure typedef defined for that SFR, where
the name of the structure typedef is the name of the register with bits_t appended
– for example, __WDTCONbits_t. The individual bits (or bit fields) are named in the
structure using the names in the data sheet. For example in the PIC32MX360F512L
processor-specific header file, the WDTCON register for use with C is declared as:
