Switch Global Interrupt Mask Register (SW_IMR)
This read/write register contains the global interrupt mask for the switch fabric interrupts. All switch
related interrupts in the
register. An interrupt is masked by setting the corresponding bit of this register. Clearing a bit will
unmask the interrupt. When an unmasked switch fabric interrupt is generated in the
