Notes to Table 2–44:
(1) This clock is user-supplied to the remote system upgrade circuitry. If you are using the ALTREMOTE_UPDATE
megafunction, the clock user-supplied to the ALTREMOTE_UPDATE megafunction must meet this specification.
(2) This is equivalent to strobing the reconfiguration input of the ALTREMOTE_UPDATE megafunction high for the
minimum timing specification. For more information, refer to the “Remote System Upgrade State Machine”
section in the Device Interfaces and Integration Basics for Arria V Devices chapter.
(3) This is equivalent to strobing the reset timer input of the ALTREMOTE_UPDATE megafunction high for the
minimum timing specification. For more information, refer to the “User Watchdog Timer” section in the Device
Interfaces and Integration Basics for Arria V Devices chapter.
