Fast Read Quad I/O (EBh) in QPI Mode
The Fast Read Quad I/O instruction is also supported in QPI mode, as shown in Figure 15c. When QPI
mode is enabled, the number of dummy clocks is con figured by the “Set Read Parameters (C0h)”
instruction to accommodate a wide range applications 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 2, 4, 6 or 8. The default number of dummy clocks
upon power up or after a Reset instruction is 2. In QPI mode, the “Continuous Read Mode” bits M7 -0 are
also considered as dummy clocks. In the default setting, the data output will follow the Continuous Read
Mode bits immediately.
“Continuous Read Mode” feature is also available in QPI mode for Fast Read Quad I/O instruction.
Please refer to the description on previous pages.
“Wrap Around” feature is not available in QP I mode for Fast Read Quad I/O instruction. To perform a read
operation with fixed data length wrap around in QPI mode, a dedicated “Burst Read with Wrap” (0Ch)
instruction must be used. Please refer to 7.2.39 for details.
