2008-11-02tx4938ide: Check minimum cycle time and SHWT range (v2)Atsushi Nemoto
SHWT value is used as address valid to -CSx assertion and -CSx to -DIOx assertion setup time, and contrarywise, -DIOx to -CSx release and -CSx release to address invalid hold time, so it actualy applies 4 times and so constitutes -DIOx recovery time. Check requirement of the recovery time and cycle time. Also check SHWT maximum value.
