External Bus Interface
Static Memory Controller
System Interrupt
External Interrupts
The System Interrupt is the wired-OR of the interrupt signals coming from:
The clock of these peripherals cannot be controlled and the Peripheral ID 1 can only be used
within the Advanced Interrupt Controller.
All external interrupt signals, i.e., the Fast Interrupt signal FIQ or the Interrupt signals IRQ0 to
IRQ6, use a dedicated Peripheral ID. However, there is no clock control associated with these
peripheral IDs.
