SPECIAL CONSIDERATIONS WITH

MICROCHIP MPLAB® IDE TOOLS

The latest versions of Microchip’s software tools have

been designed to fully support the extended instruction

set of the PIC18F2682/2685/4682/4685 family of

devices. This includes the MPLAB C18 C compiler,

MPASM assembly language and MPLAB Integrated

Development Environment (IDE).

When

selecting

target

device

for

software

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 developed to

take advantage of the extended instruction set, XINST

must be set during programming.

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

environment, that allows the user to configure the

language tool and its settings for the project

• 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

information.
