Processor-related Features
3.2.1 Processor Support
HI-TECH PICC-18 STD supports the full range of Microchip PIC 18 processors. Additional code-
compatible processors may be added by editing the picc-18.ini file in the DAT directory. User-
defined processors should be placed at the end of the file. The header of the file explains how
to specify a processor. Newly added processors will be available the next time you compile by
selecting the name of the new processor on the command line in the usual way.
3.2.2 Configuration Fuses
The PIC18 processors have several locations which contain the configuration bits or fuses. These
bits may be set using the configuration macro. The macro has the form:
(there are two leading underscore characters) where n is the configuration register number and x is
the value that is to be the configuration word. The macro is defined in <htc.h> so be sure to include
that into each module that uses this macro.
16 bits with each call. Special named quantities are defined in the header file appropriate for the
processor you are using to help you enable the required features. To look up the available attributes
for any particular chip, consult Appendix

Note that the individual selections are ANDed together. Any bits which are not selected in these
macros will remain unprogrammed. You should ensure that you have specified all bits correctly
to ensure proper operation of the part when programmed. Consult your PIC18 datasheet for more
details.
