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.
