SPI Flash memory read or write cycle

When writing then reading from an SPI flash memory there is no data.

Is there a way to tell when in a Read cycle that the cycle begins? it will read by sending a command, then address, will have a scope on the Q output and clock and hope to see some kind of data. But when in the READ cycle is the data valid on Q output?

What Chip/IC family/model of SPI flash are you working with?

@brad94538 so this is nice generic spi nor flash…

From the micro controller side, after sending the command, you still need to clock the spi bus to get the response out of the M25P80.

From what OS, or system, or mcu are you trying to access the M25P80 from?
