Interrupt Structure
The Ethernet interrupt is conceptually equivalent to the LAN91C94 interrupt line, it is the or function of all
enabled interrupts within the Ethernet core. The enabling, reporting, and clearing of these sources is
controlled by the ECOR register. The interrupt structure is similar for LOCAL BUS and PCMCIA modes
with the following exceptions:
PCMCIA uses a single interrupt pin (nIREQ) while LOCAL BUS can use any of four INTR0-3 pins.
