This function checks if the POR (Power on Reset) bit in the Diagnostic Status Register is set.
It is a separate function from the d20_check_int() because this event occurs only once
during the particular network session.
As a result of this routine the D20_POR_CNT diagnostic counter is incremented.
A designer may choose to remove this code from the final application if checking for this
status is not required in the real-life control application.
