Revision 1.19 – June 17, 2009
460EX – PPC460EX Embedded Processor
Preliminary Data Sheet
Universal Interrupt Controller (UIC)
Universal Interrupt Controllers (UICs) provide control, status, and communications necessary between the external
and internal sources of interrupts and the on-chip PowerPC processor.
Note: Processor specific interrupts (for example, page faults) do not use UIC resources.
Features include:
• Sixteen external interrupts
• Edge triggered or level-sensitive
• Positive or negative active
• Non-critical or critical interrupt to the on-chip processor
• Programmable interrupt priority ordering
• Programmable critical interrupt vector for faster vector processing
JTAG
Features include:
• IEEE 1149.1 Test Access Port
• JTAG Boundary Scan Description Language (BSDL)
• IBM RISCWatch support
