Chapter 7. Device Support Files
This section discusses device support files used in support of compilation using the
MPLAB C Compiler for PIC24 MCUs and dsPIC ® DSCs (formerly MPLAB C30).
Items discussed in this chapter are:
• Processor Header Files
• Register Definition Files
• Using SFRs
• Using Macros
• Accessing EEDATA from C Code - dsPIC30F dSCs only
7.3 PROCESSOR HEADER FILES
The processor header files are distributed with the language tools. These header files
define the available Special Function Registers (SFR’s) for each dsPIC DSC device. To
use a header file in C, use;
#include
where xxxx corresponds to the device part number. The C header files are distributed
in the support\h directory.
Inclusion of the header file is necessary in order to use SFR names
(e.g., CORCONbits).
For example, the following module, compiled for the dsPIC30F2010 part, includes two
functions: one for enabling the PSV window, and another for disabling the PSV window.
#include
void
EnablePSV(void)
{
CORCONbits.PSV = 1;
}
void
DisablePSV(void)
{
CORCONbits.PSV = 0;
}
