Instruction Set
8.1.5
The s-i-b fields provide scale factor, indexing, and a base field for address selection. The ss, index, and base fields are
described next.
8.1.5.1
The ss field (Table 8-13) specifies the scale factor used in the offset mechanism for address calculation. The scale factor
multiplies the index value to provide one of the components used to calculate the offset address.
8.1.5.2
The index field (Table 8-14) specifies the index register used by the offset mechanism for offset address calculation. When
no index register is used (index field = 100), the ss value must be 00 or the effective address is undefined.
