Switch Global Interrupt Pending Register (SW_IPR)
This read-only register contains the pending global interrupts for the Switch Fabric. A set bit indicates
an unmasked bit in the corresponding Switch Fabric sub-system has been triggered. All switch related
interrupts in this register may be masked via the
register. When an unmasked Switch Fabric interrupt is generated in this register, the interrupt will
trigger the
