description: |
IA55 performs various interrupt controls including synchronization for the external
interrupts of NMI, IRQ, and GPIOINT and the interrupts of the built-in peripheral
interrupts output by each IP. And it notifies the interrupt to the GIC
- IRQ sense select for 8 external interrupts, mapped to 8 GIC SPI interrupts
- GPIO pins used as external interrupt input pins, mapped to 32 GIC SPI interrupts
- NMI edge select (NMI is not treated as NMI exception and supports fall edge and
stand-up edge detection interrupts)
