The INIT_DONE pin indicates the device has enter user mode upon completion of configuration. When used for this purpose, this pin must be enabled by the Intel^® Quartus^® Prime software.

When the INIT_DONE function is enabled, this pin will drive high when configuration is completed and the device goes into user mode.

Intel^® recommends you to use SDM_IO0 or SDM_IO16 to implement the INIT_DONE function when available as it has an internal weak pull-down for the correct function of INIT_DONE during power up.

If SDM_IO0 and SDM_IO16 are unavailable, SDM_IO5 can also be used for the INIT_DONE function when the configuration mode is set to Avalon^® –ST x8 or Avalon^® –ST x32 (AVST x8 or AVST x32) as these modes require an external 4.7–kΩ pull-down resistor.

If SDM_IO0, SDM_IO5, and SDM_IO16 are unavailable, the INIT_DONE function can also be implemented using any unused SDM_IO pins provided that an external 4.7–kΩ pull-down resistor is provided for the INIT_DONE signal.

This is an active low, bidirectional pin. By default, this pin acts as an input pin to the SDM. When asserted externally for at least 5ms, this pin will generate interrupt to the SDM. The SDM will then initiate a cold reset procedure to the HPS and its peripherals.

Direct to factory input pin.

When using the remote system upgrade feature, this optional pin allows you to choose between factory or application image. Driving logic high into this pin will instruct the device to load factory image, while driving logic low into this pin will instruct the device to load the application image.

Connect this input pin to an external logic device that manages the remote system upgrade of the device. By default, the external logic should provide logic low to this pin so that the application image will be the default image of the device, and only switch to factory image if required.
