  --- following RESET:                                              
                            PMWAIT =   0x0003de

      this implies RESET is equivalent to:                          
      --- internal 7 cycles min, extendable by hardware             
      e.g.                                                          
      PMWAIT = xMWAIT_Internal_Min_External_More<<xMWAIT_Mode_Bank0 | 7<<xMWAIT_Count_Bank0 \
             | xMWAIT_Internal_Min_External_More<<xMWAIT_Mode_Bank1 | 7<<xMWAIT_Count_Bank1;
      DMWAIT = xMWAIT_Internal_Min_External_More<<xMWAIT_Mode_Bank0 | 7<<xMWAIT_Count_Bank0 \
             | xMWAIT_Internal_Min_External_More<<xMWAIT_Mode_Bank1 | 7<<xMWAIT_Count_Bank1 \
             | xMWAIT_Internal_Min_External_More<<xMWAIT_Mode_Bank2 | 7<<xMWAIT_Count_Bank2 \
             | xMWAIT_Internal_Min_External_More<<xMWAIT_Mode_Bank3 | 7<<xMWAIT_Count_Bank3;
                                                                    
      another example --- internal 0 cycles only                    
      PMWAIT = xMWAIT_Internal_Only<<xMWAIT_Mode_Bank0 | 0<<xMWAIT_Count_Bank0 \
             | xMWAIT_Internal_Only<<xMWAIT_Mode_Bank1 | 0<<xMWAIT_Count_Bank1;
      DMWAIT = xMWAIT_Internal_Only<<xMWAIT_Mode_Bank0 | 0<<xMWAIT_Count_Bank0 \
             | xMWAIT_Internal_Only<<xMWAIT_Mode_Bank1 | 0<<xMWAIT_Count_Bank1 \
             | xMWAIT_Internal_Only<<xMWAIT_Mode_Bank2 | 0<<xMWAIT_Count_Bank2 \

      another example --- internal 0 cycles only, except 
                          external acknowledge for port in DM bank 1, 
                          internal 5 cycles for port in DM bank 2,
                          other non-zero banks not used                    
      PMWAIT = xMWAIT_Internal_Only<<xMWAIT_Mode_Bank0 | 0<<xMWAIT_Count_Bank0;
      DMWAIT = xMWAIT_Internal_Only<<xMWAIT_Mode_Bank0 | 0<<xMWAIT_Count_Bank0 \

             | xMWAIT_Internal_Only<<xMWAIT_Mode_Bank2 | 5<<xMWAIT_Count_Bank2;
                                                                    
      another example --- all external only                         
      PMWAIT = 0
