Figure 42. FlexSPI input timing in SDR mode where FlexSPIn_MCR0[RXCLKSRC] = 0x3 (Case A2)

NOTE

Timing shown is based on the memory generating read data on the SCK

falling edge and read strobe on the SCK rising edge. The FlexSPI controller

samples read data on a half-cycle delayed DQS falling edge.
