7.33.

Set Read Parameters (C0H)

In QPI mode t

he “Set Read Parameters (C0H)” command can be used to configure the number of dummy clocks for

“Fast Read (0BH)”, “Quad I/O Fast Read (EBH)” and “Burst Read with Wrap (0CH)” command, and to configure the

number of bytes of “Wrap Length” for the “Burst Read with Wrap (0CH)” command. The “Wrap Length” is set by W5-6 bit in

the “Set Burst with Wrap (77H)” command. This setting will remain unchanged when the device is switched from Standard

SPI mode to QPI mode.
