Description
Each interrupt request bit is correspondent to a page entry in the lower half of
the Upstream Memory 2 range. Bit [0] is for the 33
the 64
transfers data to or from the initiator that addresses the last Double Word in a
page. PI7C9X130 initiates an interrupt request on secondary interface when
the interrupt request bit is set and the corresponding Upstream Page Boundary
IRQ 1 Mask bit is reset. When forward bridge, PI7C9X130 asserts INTA_L or
generates MSI on secondary bus (PCI interface). When reverse bridge,
PI7C9X130 sends INTA_L assertion message or generates MSI on secondary
interface (PCI Express).
When wrting a “1” to this register, it clears the corresponding interrupt request
bit.
Reset to 0
