QSPI — Quad serial peripheral interface - Nordic Semiconductor
Webread, the SDIO line is transitioned from an input to an output within one half of a clock cycle. This ensures that by the time the falling edge of the next clock cycle occurs, data can be safely placed on this serial line for the controller to read. If the external controller is insufficiently fast to keep up with the ADC SPI WebUnderstanding Dummy Clock Cycles for Single and Quad IO Fast Read Third-party quad SPI flash devices may have fixed or configurable dummy clock cycles.
