- * The PowerPC 403 cores' Asynchronous Interrupt Controller (AIC) has
- * 32 possible interrupts, a majority of which are not implemented on
- * all cores. There are six configurable, external interrupt pins and
- * there are eight internal interrupts for the on-chip serial port
- * (SPU), DMA controller, and JTAG controller.
