      Due to the special implementation of the eSDHC, there are constraints regarding the clock and data signals
      propagation delay on the user board. The constraints are for minimum and maximum delays, as well as
      skew between the CLK and DAT/CMD signals.
      In full speed mode, there is no need to add special delay on the data or clock signals. The user should make
      sure to meet the timing requirements as described further within this document.
      If the system is designed to support both high-speed and full-speed cards, the high-speed constraints
      should be fulfilled. If the systems is designed to operate up to 25 MHz only, full-speed mode is
      recommended.
