2.2.18 Immediate Data
In this addressing mode, the operand is in one or two extension words. Table 2-3 lists the
location of the operand within the instruction word format. The immediate data format is as
follows:
2.3 EFFECTIVE ADDRESSING MODE SUMMARY
Effective addressing modes are grouped according to the use of the mode. Data addressing
modes refer to data operands. Memory addressing modes refer to memory operands.
Alterable addressing modes refer to alterable (writable) operands. Control addressing
modes refer to memory operands without an associated size.
These categories sometimes combine to form new categories that are more restrictive. Two
combined classifications are alterable memory (addressing modes that are both alterable
and memory addresses) and data alterable (addressing modes that are both alterable and
data). Table 2-4 lists a summary of effective addressing modes and their categories.
