Development Tools and Support
Each module operates completely independent of its environment. Independence from the
hardware environment is achieved by the fact that each module is individually configurable
and relocatable anywhere in system memory. Calls are used for requesting resources or
services from the host operating system (memory management and message passing),
which creates independence from the firmware. Modules may be used with any combination
of other modules, including those added by the user (see Figure B-1).
The chip driver module features are as follows:
B-2
• All software modules use the driver module as their interface to the MC68302
