Measurement is with a load of 35 pF on SCK and SIO pins and an input slew rate of 1 V/ns.
3.9.10.1 SDR Mode
Figure 32. QuadSPI input/read timing (SDR mode with internal sampling)
Figure 33. QuadSPI input/read timing (SDR mode with loopback DQS sampling)
NOTE
• For internal sampling, the timing values assume using sample point 0,
that is QuadSPIx_SMPR[SDRSMP] = 0.
