Hardware Description

The primary interrupt controller manages interrupts from internal devices and provides 11 pins for use by the external secondary interrupt controller and multiplexor present in the FPGA. VICINTSOURCE31 is the output from the secondary controller.

VICINTSOURCE[30:21] can be driven from individual interrupt signals from peripherals in the FPGA or on a RealView Logic Tile.

For details on the programming model for the interrupt controllers, see:

the ARM926EJ-S Development Chip Reference manual
