PIC18F2450/4450
19.2.5
The latest versions of Microchip’s software tools have
been designed to fully support the extended instruction
set of the PIC18F2450/4450 family of devices. This
includes the MPLAB C18 C compiler, MPASM
Assembly
Development Environment (IDE).
When
development, MPLAB IDE will automatically set default
Configuration bits for that device. The default setting for
the XINST Configuration bit is ‘0’, disabling the
extended instruction set and Indexed Literal Offset
Addressing mode. For proper execution of applications

To develop software for the extended instruction set,
the user must enable support for the instructions and
the Indexed Addressing mode in their language tool(s).
Depending on the environment being used, this may be
done in several ways:
• A menu option, or dialog box within the
• A command line option
• A directive in the source code
These options vary between different compilers,
assemblers and development environments. Users are
encouraged to review the documentation accompany-
ing their development systems for the appropriate
