MODIFICATION HISTORY:

Ver   Who  Date     Changes
----- ---- -------- -----------------------------------------------
1.01a rfp  10/19/01 release
1.01c ecm  12/05/02 new rev
1.13a wgr  03/22/07 Converted to new coding style.
2.00a sdm  10/22/09 Converted all register accesses to 32 bit access.
          Removed the macro XIIC_CLEAR_STATS, user has to
          use the the XIic_ClearStats API in its place.
          Removed the macro XIic_mEnterCriticalRegion,
          XIic_IntrGlobalDisable should be used in its place.
          Removed the macro XIic_mExitCriticalRegion,
          XIic_IntrGlobalEnable should be used in its place.
          Removed the _m prefix from all the macros
          XIic_mSend10BitAddrByte1 is now XIic_Send10BitAddrByte1
          XIic_mSend10BitAddrByte2 is now XIic_Send10BitAddrByte2
