Macros
Macros to access all of the registers are defined in altera_vic_regs.h. For example, this file includes
macros to access the
INT_CONFIG
register, including the following macros:
#define IOADDR_ALTERA_VIC_INT_CONFIG(base, irq) __IO_CALC_ADDRESS_NATIVE(base,
irq)
#define IORD_ALTERA_VIC_INT_CONFIG(base, irq) IORD(base, irq)
#define IOWR_ALTERA_VIC_INT_CONFIG(base, irq, data) IOWR(base, irq, data)
#define ALTERA_VIC_INT_CONFIG_RIL_MSK (0x3f)
#define ALTERA_VIC_INT_CONFIG_RIL_OFST (0)
#define ALTERA_VIC_INT_CONFIG_RNMI_MSK (0x40)
#define ALTERA_VIC_INT_CONFIG_RNMI_OFST (6)
#define ALTERA_VIC_INT_CONFIG_RRS_MSK (0x1f80)
#define ALTERA_VIC_INT_CONFIG_RRS_OFST (7)
