2.5.3. Device Configuration Pins for Optional Configuration Signals
All configuration schemes use the same dedicated pins for the standard control signals shown in the Intel Agilex Configuration
Timing Diagram. Many other optional configuration signals do not have dedicated pin assignments.
Device Configuration Pins without Fixed Assignments
Note:
Although the CONF_DONE and INIT_DONE configuration signals are not required, Intel recommends that you use these
signals as an indicator to ensure that configuration is successful. The SDM drives the CONF_DONE signal high after
successfully receiving full bitstream. The SDM drives the INIT_DONE signal high to indicate the device is fully in user mode.
These signals are important when debugging configuration.
