QSPI connection

Question

In the datasheet of AD5421, it's said that the device could support QSPI connection. 
 But what pin is for IO0 to IO4 for QSPI? 
 Could you please offer hardware connection schematic for QSPI? 
 Thanks.

Hi howardaaa , 
 Depending on the controller used, you only need two IOs (i.e. IO0 and IO1) and set them as SDIN and SDO line functionality. 
 IO2 and IO3 won't be needed. 
 This means that the part can be connected with a QSPI peripheral but will not be able to operate in full QSPI mode.
