Interrupt Handling
ThunderLAN and its host device indicate communication with each other by
sending and receiving interrupts to the bus data stream. This chapter provides
information on setting up code which recognizes, prioritizes, and acknowl-
edges these interrupts. It defines specific interrupt codes and describes what
happens when these occur. This allows the user to diagnose and correct any
conditions which may cause failure.
