Note: Signal integrity can be improved by adding series resistors on each QSPI line. The resistor value should be based on the corresponding I/O pin drive strength (decided by PINCFGn.DRVSTR) and PCB trace impedance. It is recommended to do simulation using the device IBIS files to choose the correct termination and PCB trace impedance combination.
