Data Sheet
PowerPC 440SP Embedded Processor
Universal Interrupt Controller (UIC)
Two cascaded Universal Interrupt Controllers (UIC) process internal on-chip and external processor interrupts.
Note: Processor specific interrupts (for example, page faults) do not use UIC resources.
Features include:
• 6 external interrupts
• 56 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)
