VER 1.1

Set Read Parameters (C0H)

In QPI mode the “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
