IOWR_ALTERA_RU_PAGE_SELECT (REMOTE_UPDATE_BASE, start address); //start address

IOWR_ALTERA_RU_WATCHDOG_TIMEOUT (REMOTE_UPDATE_BASE, 0x00000001); //set the watch down timeout

IOWR_ALTERA_RU_WATCHDOG_ENABLE (REMOTE_UPDATE_BASE, ALTERA_RU_WATCHDOG_ENABLE); //enable the watchdog

IOWR_ALTERA_RU_RECONFIG (REMOTE_UPDATE_BASE, 0x01); //trigger the reconfiguration
