AM9519A
Universal Interrupt Controller
The AM9519A Universal Interrupt Controller is a processor support circuit that provides a powerful
interrupt structure to increase the efficiency and versatility of microcomputer-based systems. A single
AM9519A manages up to eight maskable interrupt request inputs, resolves priorities and supplies
up to four bytes of fully programmable response for each interrupt. It uses a simple expansion
structure that allows many units to be cascaded for control of large numbers of interrupts. Several
programmable control features are provided to enhance system flexibility and optimization.
