title: Aspeed AST2700 Interrupt Controller
|
||||
|
||||
description:
|
||||
This interrupt controller hardware is second level interrupt controller that
|
||||
is hooked to a parent interrupt controller. It's useful to combine multiple
|
||||
interrupt sources into 1 interrupt to parent interrupt controller.

Depend to which INTC0 or INTC1 used.
|
||||
INTC0 and INTC1 are two kinds of interrupt controller with enable and raw
|
||||
status registers for use.
|
||||
INTC0 is used to assert GIC if interrupt in INTC1 asserted.
|
||||
INTC1 is used to assert INTC0 if interrupt of modules asserted.
