2.5 EFFECTIVE ADDRESS ENCODING SUMMARY
2-22
word. The encoding of the mode field of this word selects the addressing
the instruction word followed by the brief format extension word. Other
of extension words. The longest instruction for the MC68030 contains 10
for both the source and destination effective addresses and with 32-bit base
displacements and 32-bit outer displacements for both addresses. However,
coprocessor instructions can have any number of extension words. Refer to
the coprocessor instruction formats in SECTION 10 C O P R O C E S S O R INTER-
sponding to all combinations of IS and I/IS values.
2-4. The single effective address instruction is in the format of the instruction
mode. The register field contains the general register number or a value that
selects the addressing mode when the mode field contains " 1 1 1 " . Table
2-2 shows the encoding of these fields. Some indexed or indirect modes use
indexed or indirect modes consist of the instruction word and the full format
extension words. It is a MOVE instruction with full format extension words
FACE DESCRIPTION.
For effective addresses that use the full format, the index suppress (IS) bit
and the index/indirect selection (I/IS) field determine the type of indexing and
indirection. Table 2-1 lists the indexing and indirection operations corre-
Most of the addressing modes use one of the three formats shown in Figure
