Interrupt request 0–11. The polarity and sense of each of these signals is programmable. All of these inputs
can be driven asynchronously. The interrupt request signals IRQn may share PIC external interrupt registers
with PCI Express INTx signaling. See
Interrupt request out. Active-low, open drain. When the PIC is programmed in pass-through mode, this output
reflects the raw interrupts generated by on-chip sources. See
details.
Machine check processor. Assertion causes a machine check interrupt to the e500 core. Note that if the e500
core is not configured to process machine check interrupts (MSR[ME] = 0), assertion of MCP causes a
checkstop condition. Note that internal sources for the internal core_mcp signal can also cause a machine
check interrupt to the processor core, as described in
(MCPSUMR),” Table 10-1
Unconditional debug event. Assertion signal causes an unconditional debug exception to the e500 core.

Table 10-5. Interrupt Signals—Detailed Signal Descriptions
Asserted—When an external interrupt signal is asserted (according to the programmed polarity),
Negated—There is no incoming interrupt from that source.
Negation—Interrupts programmed as level-sensitive must remain asserted until serviced.
Asserted—At least one interrupt is currently being signaled to the external system.
Negated—Indicates no interrupt source currently routed to IRQ_OUT.
negation of IRQ_OUT occurs asynchronously with respect to the interrupt source. All timing given
here is approximate.
Assertion—Internal interrupt source: 2 CCB clock cycles after interrupt occurs.
Negation—Follows interrupt source negation with the following delay:
Asserted—Integrated logic should initiate a machine check interrupt or enter the checkstop state
Negated—Machine check handling is not being requested by the external system.
Negation—Because MCP is edge-triggered, it can be negated one clock after its assertion.
Asserted—Indicates that integrated logic should initiate an unconditional debug event interrupt to
Negated—Indicates that unconditional debug event handling is not being requested by UDE.
Negation—Should remain asserted until software in the unconditional debug event interrupt
the priority is checked by the PIC unit, and the interrupt is conditionally passed to the
processor. In pass-through mode, only interrupts detected on IRQ0 are passed directly to the
processor core.
External interrupt source: 4 cycles after interrupt occurs.
Message interrupts: 2 cycles after write to message register.
Internal interrupt: 2 CCB clock cycles
External interrupt: 4 cycles.
Message interrupts: 2 cycles after message register cleared.
