FlexSPI output/write timing

The following sections describe output signal timing for the FlexSPI controller including control signals

and data outputs.

4.5.2.2.1

SDR mode

NOTE

TCSS and TCSH are configured by the FlexSPIn_FLSHAxCR1 register, the

default values are shown above. Please refer to the i.MXRT1170 Reference

Manual (IMXRT1170RM) for more details.
