#FILL_ROM
Syntax:
Elements:
Purpose:
Examples:
#fill_rom value
value is a constant 16-bit value
This directive specifies the data to be used to fill unused ROM locations. When
linking multiple compilation units, this directive must appear exactly the same in
each compilation unit.
#fill_rom 0x36
Example Files: None

#FUSES
Syntax:
#ROM
#FUSES options
Elements: options vary depending on the device. A list of all valid options has been put at the
top of each devices .h file in a comment for reference. The PCW device edit utility
can modify a particular devices fuses. The PCW pull down menu VIEW | Valid fuses
will show all fuses with their descriptions.
Some common options are:
? LP, XT, HS, RC
? WDT, NOWDT
? PROTECT, NOPROTECT
? PUT, NOPUT (Power Up Timer)
? BROWNOUT, NOBROWNOUT
Purpose:
This directive defines what fuses should be set in the part when it is
programmed. This directive does not affect the compilation; however, the
information is put in the output files. If the fuses need to be in Parallax format, add a
PAR option. SWAP has the special function of swapping (from the Microchip
standard) the high and low BYTES of non-program data in the Hex file. This is
required for some device programmers.
Some fuses are set by the compiler based on other compiler directives. For
example, the oscillator fuses are set up by the #USE delay directive. The debug,
No debug and ICSPN Fuses are set by the #DEVICE ICD=directive.
Some processors allow different levels for certain fuses. To access these levels,
assign a value to the fuse. For example, on the 18F452, the fuse PROTECT=6
