1 The actual maximum frequency supported is limited by the FlexSPIn_MCR0[RXCLKSRC] configuration used. See the

FlexSPI SDR input timing specifications.

NOTE

TCSS and TCSH are configured by the FlexSPIn_FLSHAxCR1 register, the

default values are shown above. See the i.MX 8M Plus Applications

Processor Reference Manual (IMX8MPRM) for more details.
