3.1.2. Understanding Dummy Clock Cycles for Single and Quad IO Fast Read

Table 3.  Flash Commands for Configuration Control Block
Command Opcode Dummy Clock Cycles Dependency
Normal Read 0x03 No
Single IO Fast Read 0x0B Yes
Quad IO Fast Read 0xEB Yes

Third-party quad SPI flash devices may have fixed or configurable dummy clock cycles. Determine the number of dummy clock cycles for the 0x0B and 0xEB commands from the third-party quad SPI flash datasheet for you to generate the .rpd file for your design.
