[1] These timing specifications are valid only for 1.8 V nominal I/O pad supply voltage. For 3.3 V I/O supply, see Table 89

[2] The maximum frequency supported is 56 MHz when NVCC_xxxx operating at 3.3 V.

[3] TCSS and TCSH are configured by the FlexSPIn_FLSHAxCR1 register. See i.MX 93 Applications Processor Reference Manual (IMX93RM) for more details.
