Programmable interrupt controller (PIC)
— Programming model is compliant with the OpenPIC architecture.
— Supports 16 programmable interrupt and processor task priority levels
— Supports 12 discrete external interrupts
— Supports 4 message interrupts with 32-bit messages
— Supports connection of an external interrupt controller such as the 8259 programmable
— Four global high resolution timers/counters that can generate interrupts
— Supports a variety of other internal interrupt sources
— Supports fully nested interrupt delivery
— Interrupts can be routed to external pin for external processing.
— Interrupts can be routed to the e500 core’s standard or critical interrupt inputs.
— Interrupt summary registers allow fast identification of interrupt source.
