CONFIGURATION

The following parameters of the DP80390 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.

- synchronous

Besides mentioned above parameters all

available peripherals and external interrupts

can be excluded from the core by changing

appropriate constants in package file.
