Note: The USB interface supports single data rate (SDR) timing only.
Note: If you need to adjust the timings of certain signals, you can use the HPS registers Pin_Mux.io0_delay through Pin_Mux.io47_delay to allow software to set the delay chains in each of the dedicated I/Os. For example, to add output and input delay to the USB_DATA3 signal (HPS_IOA_8), program Pin_Mux.io7_delay.output_val_en = 1, and Pin_Mux.io7_delay.output_val = 15 to add approximately 1.4 ns output delay from the HPS, and program Pin_Mux.io7_delay.input_val_en = 3, and Pin_Mux.io7_delay.input_val = 30 to add approximately 2.8 ns input delay into the HPS. See HPS Programmable I/O Timing Characteristics for more information.
