Hi Guenter,
It is a point of view. One could also say:
A VP is a bunch of code and data, that makes up a logic unit, aka peripheral, with a well defined
software interface, by which the application communicates with the peripheral.

The best examples in my library not using isr code, are the queue and stack.
Both have a data area and two subroutines to store and retrieve data. How these
are implemented is of no concern of the application. The functions are well defined
and that's what the application uses.
 

regards peter
