PICC18 Compiler Options
will not be performed if the --FILL option is also used to allow a different code to be used for
prefilling.
2.4.22 --CHIP=processor: Define Processor
This option defines the processor which is being used. To see a list of supported processors that can
be used with this option, use the --CHIPINFO option.
2.4.23 --CHIPINFO: Display List of Supported Processors
The --CHIPINFO option simply displays a list of processors the compiler supports. The names listed
are those chips defined in the chipinfo file and which may be used with the --chip option or refer
to Appendix
2.4.24 --CODEOFFSET: Offset Program Code to Address
In some circumstances, such as bootloaders, it is necessary to shift the program image to an alternate
address. This option is used to specify a base address for the program code image. With this option,
all code psects (including interrupt vectors and constant data) that the linker would ordinarily control
the location of, will be adjusted.
2.4.25 --CP=size: Set the Size of Pointers to Code Space
Pointers to code/functions, pointers to const, pointers to far and pointers to void can be set to either
16 bits wide or 24 bits wide. If this option is not specified the default setting is 16 bits. It is
sufficient to use --CP=16 for chips that have less than 64K of program memory, or if only the first
64K of program memory will be dereferenced with a pointer. If a particular program uses pointers
to program space beyond the 64K boundary that it is necessary to enable 24 bit code pointers. This
is also applicable to projects and PIC18 devices which utilize the external memory interface, as it is
more than likely that the additional memory will be mapped beyond the 64K boundary.
It will also be necessary to enable 24 bit pointers to reference an object in code space which is located
at an address that would also be valid in the general-purpose data space. For more information on
