1.8V Uniform Sector

Dual and Quad Serial Flash

GD25LQ128D

P[5:4] setting, the number of dummy clocks can be configured as either 4/6/8/8. In QPI mode, the

“Continuous Read Mode”

bits M7-M0 are also considered as dummy clocks.

“Continuous Read Mode” feature is also available in QPI mode for Quad

I/O Fast Read command.

“Wrap Around” feature is not available in QPI mode for Quad I/O Fast Read command. To perform

a read operation with fixed data length wrap around in QPI mode, a dedicated

“Burst Read with Wrap” (0CH) command

must be used.
