    Do you mean IOWR_ALTERA_AVALON_PIO_IRQ_MASK?

    If so, this is a macro defined in components/altera_avalon_pio/inc/altera_avalon_pio_regs.h which is used to write to the PIO interrupt mask register. More information on the use of this register can be found in the description of the PIO core in the "Peripheral Support" section of the Nios II processor Handbook. A pdf of this document is suppiled with the Nios II kit.
