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?
