CONFIGURATION
The following parameters of the DR80390 core
can be easy adjusted to requirements of dedi-
cated application and technology. Configura-
tion of the core can be prepared by effortless
changing appropriate constants in package file.
There is no need to change any parts of the
code.

- Harward
- von Neumann
• Program Memory type
- synchronous
- asynchronous
•

Besides mentioned above parameters all
available peripherals and external interrupts
can be excluded from the core by changing
appropriate constants in package file.
