Manageability Control Processor interrupt map
The
Manageability Control Processor
(MCP) receives interrupts from several sources.
The sources of the interrupts to the MCP are:
• Application Processor system wakeup interrupts
• CoreSight power and reset request interrupts
• Internal MCP subsystem interrupts
• Expansion MCP interrupts
The interrupts are routed to the Nested Vector Interrupt Controllers in Cortex
‑
M7 processors where they
can be managed by software.
The following table shows the MCP interrupts.
