MV64360 Interrupt Controller | Emerson MVME6100 guide

Programming Details

	2	PCI0 bus at 133MHz and the secondary PMCspan bus at 33 or 66 MHz.
	2	See the PLX PCI6520 Specification for further programming information.

MV64360 Interrupt Controller

The MVME6100 uses the MV64360 interrupt controller to route internal and external interrupt requests to the CPU and the PCI bus. The MV64360 interrupt controller registers are implemented as part of the CPU interface unit in order to have minimum read latency from CPU interrupt handler.

This is not backward compatible with the Discovery I implementation since the registers are placed at different offsets. The external interrupt sources will use the GPP interface to register external interrupts. The following table shows the MVME6100 interrupt assignment to MV64360 GPP pins.
