For explanation of each of these interrupts - refer to the COM2002x ULANC Data Sheet.
Note that the COM2002x will generate the interrupt only when the corresponding bits are set
in the Interrupt Mask Register.
This function can be a part of the ISR d20_interrupt() or can be invoked by the scheduler as
a result of the global flag set the ISR.
The real-life control application may require different actions upon the occurrence of any
network events than those programmed into the d20_check_int() parser. The designer may
want to tailor this parser, inserting the control software in places, where the diagnostic
counters are incremented.
