34 / 90 page W25Q16FW - 33 - Fast Read (0Bh) in QPI Mode The Fast Read instruction is also supported in QPI mode. When QPI mode is enabled, the number of dummy clocks is configured by the “Set Read Parameters (C0h)” instruction to accommodate a wide range of 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. /CS CLK Mode 0 Mode 3 0 1 IO 0 IO 1 IO 2 IO 3 0Bh 2 3 4 5 20 16 12 8 21 17 22 18 23 19 13 9 14 10 15 11 A23-16 6 7 8 9 4 0 5 1 6 2 7 3 A15-8 A7-0 Dummy * Byte 1 Byte 2 4 0 5 1 6 2 7 3 4 0 5 1 6 2 7 3 4 0 5 1 6 2 7 3 10 11 12 13 4 5 6 7 IOs switch from Input to Output * "Set Read Parameters" instruction (C0h) can set the number of dummy clocks.
