Universal Interrupt Controller (UIC)
The Universal Interrupt Controller (UIC) provides the control, status, and communications necessary between the
various sources of interrupts and the local PowerPC processor.
Features include:
10/100 Mbps Ethernet MAC
JTAG
AMCC
• Supports 13 external and 19 internal interrupts
• Edge triggered or level-sensitive
• Positive or negative active
• Non-critical or critical interrupt to processor core
• Programmable critical interrupt priority ordering
• Programmable critical interrupt vector for faster vector processing
• Capable of handling full/half duplex 100Mbps and 10Mbps operation
• Uses the medium independent interface (MII) to the physical layer (PHY not included on chip)
• IEEE 1149.1 test access port
• IBM RISCWatch debugger support
• JTAG Boundary Scan Description Language (BSDL)
• Seven of the 13 interrupts are mapped to the same GPIOs as the PPC405GP.
• The other six interrupts can be mapped to any of the GPIOs.
