 this is frequently the normally desired behaviour, see the \c{DEFAULT}

+A new form of split effective addres syntax is also supported. This is mainly
+intended for mib operand but can be used for any memory reference. The basic
+concept of this form is splitting base and index.

+For mib operands, there are several ways of writing effective address depending
