The Partial Reconfiguration External Configuration Controller IP supports partial reconfiguration via an external source.
When using external configuration, you must connect all the top-level ports of the Partial Reconfiguration External Configuration Controller IP to the pr_request and status pins. These connections allow the handshaking of the host with the SDM from the Agilex™ FPGA Portfolio or Stratix® 10 device core. The SDM determines which types of configuration pins to use, according your MSEL setting.
