SPECIAL FUNCTION REGISTER ACCESS
CP0 REGISTER ACCESS
There are three steps to follow when using SFRs in an application.
1. Include either the generic processor header file (i.e., p32xxxx.h) or the
2. Access SFRs like any other C variables. The source code can write to and/or
3. Link with the default linker script or include the processor.o file for the
4.7.1
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. The CP0 register definitions 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. The CP0 register definitions header file was designed to
work with either Assembly or C files.
The CP0 register definitions header file is dependent on macros defined within the
processor generic header file (See Section 4.3 “Generic Processor Header File”).
To include the CP0 register definitions header file, use the following from within your
source code:
4.7.2
When the CP0 register definitions header file is included from an Assembly file, the
CP0 registers are defined as:
For example, the IntCtl register is defined as:
When the CP0 register definitions header file is included from a C file, the CP0 registers
and selects are defined as:
For example, the IntCtl register is defined as:
4.7.3
When the CP0 register definitions header file is included from either an Assembly or a
C file, three #defines exist for each of the CP0 register fields.
_CP0_
processor-specific header file for the appropriate device (e.g.,
proc/p32mx360f512l.h).
#include <p32xxxx.h>
read from the SFRs. For example, the following statement clears all the bits to
zero in the special function register for Timer 1:
TMR1 = 0;
The next statement enables the Watchdog Timer:
WDTCONbits.ON = 1;
appropriate processor in your project.
#include <p32xxxx.h>
#define _CP0_
#define _CP0_INTCTL $12, 1
#define _CP0_
#define _CP0_
#define _CP0_INTCTL 12
#define _CP0_INTCTL_SELECT 1
