Each OCT block has one RZQ pin.
- RZQ pins are dual-purpose pins. If the pins are not connected to the OCT block, you can use the pins as regular I/O pins.
- Calibrated pins must have the same VCCIO voltage as the OCT block and the RZQ pin. Calibrated pins connected to the same OCT block must have the same series and parallel termination values.
- You can apply location constraints on the RZQ pins to determine the placement of the OCT block because the RZQ pin can only be connected to its corresponding OCT block.
