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.  
User Watchdog Internal Oscillator Frequency Specification  
Table 2–45 lists the frequency specifications for the user watchdog internal oscillator.
