1.8V Uniform Sector

Dual and Quad Serial Flash

GD25LB128D

7.32.

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.
