Revision 1.07 – October 4, 2007
440GP – Power PC 440GP Embedded Processor
Data Sheet
Universal Interrupt Controller (UIC)
TwoUniversal Interrupt Controllers (UIC) are available. They 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:
• 13 external interrupts
• 45 internal interrupts
• Edge triggered or level-sensitive
• Positive or negative active
• Non-critical or critical interrupt to the on-chip processor core
• Programmable interrupt priority ordering
• Programmable critical interrupt vector for faster vector processing
JTAG
Features include:
• IEEE 1149.1 Test Access Port
• IBM RISCWatch Debugger support
• JTAG Boundary Scan Description Language (BSDL)
