MicroBlaze Interrupts

The 32 external interrupt input signals that can be wired to the MicroBlaze wrapper's Peripheral I/O Interface (the interface of the wrapper around the processor) are connected internally to the MicroBlaze's actual Interrupt port. The Xilinx Interrupt Handler is then used to process an interrupt. See the MicroBlaze Processor Reference Guide for more information, available from www.xilinx.com/microblaze.
