7.4.3. Remote System Upgrade Circuitry

The remote system upgrade circuitry contains the remote system upgrade registers, watchdog timer, and a state machine that controls these components.

Note: If you are using the Altera Remote Update IP core, the IP core controls the RU_DOUT , RU_CTL[1:0] , RU_CLK , RU_DIN , RU_nCONFIG , and RU_nRSTIMER signals internally to perform all the related remote system upgrade operations.
