Does some one know the SDHC spec. of i.MX31?

There are input setup/hold time of SDHC in data sheet. However, it specify max value of setup/hold time like below.

SDHC input setup MAX  18.5nS, SDHC input hold MAX -11.5nS.

Usually, setup/hold time should be minimum  value not MAX.

Could you teach min value of setup/hold time?
