10.12 Read Data Bytes at Higher Speed in QPI mode

The Fast Read command is also supported in QPI mode. In QPI mode, the number of dummy clocks is

configured by the “Set Read Parameters (C0H)” command to accommodate a wide range application with

different needs for either maximum Fast Read frequency or minimum data access latency. Depending on the

Read Parameter Bits P[5:4] setting, the number of dummy clocks can be configured as either 4/6/8.
