3.2.2. Dynamic Reconfiguration
If you enable dynamic reconfiguration, the IP provides an ARM AMBA* AXI4-Lite interface. You can use the AXI4-Lite memory-mapped interface to reconfigure the input and output delays in the PHY and calibrate the delays. Through calibration, you can optimize the delay settings to maximize the capture window. You can access the AXI4-Lite memory-mapped interface through the EMIF Calibration IP. You can connect the EMIF Calibration IP to up to two PHY Lite for Parallel Interfaces IP instances in an I/O bank.
You can reset the PHY by enabling dynamic reconfiguration and writing to the TrainReset bit. The reset_n port in PHY Lite for Parallel Interfaces IP is a global power-up reset and resets the entire interface, including the PLL, all logic states in the I/O lanes, and the PHY dynamic reconfigurable delay control/status registers (CSR) that can be reset by the TrainReset bit.
