Section FUNCTIONAL SUMMARY

Interrupt Control

The ACC controls local and VMEbus interrupts. Because the ACC allows the dynamic assignment of
local interrupts to specific request levels, a fixed interrupt map is unnecessary. The following table lists
the internal and VMEbus interrupt sources and the levels to which they may be assigned. The ACC inter-
rupt input pin for each local interrupt request is also shown.
