3.4 INSTRUCTION SET SUMMARY
Table 3–14 provides a alphabetized listing of the MC68030 instruction set listed by opcode,
operation, and syntax.
Table 3–14 use notational conventions for the operands, the subfields and qualifiers, and
the operations performed by the instructions. In the syntax descriptions, the left operand is
the source operand, and the right operand is the destination operand. The following list
contains the notations used in Table 3–14.
Notation for operands:
PC — Program counter
SR — Status register
V — Overflow condition code
Immediate Data — Immediate data from the instruction
Source — Source contents
Destination — Destination contents
Vector — Location of exception vector
+ inf — Positive infinity
–inf — Negative infinity
〈fmt〉 — Operand data format: byte (B) word (W), long
(L), single (S), double (D), extended (X), or
packed (P)
FPm — One of eight floating-point data registers (always
specifies the source register)
FPn — One of eight floating-point data registers (always
specifies the destination register)
Notation for subfields and qualifiers:
〈bit〉 of (operand〉
— Selects a single bit of the operand
〈ea〉 {offset:width} — Selects a bit field
(〈operand〉) — The contents of the referenced location
〈operand〉
10
— The operand is binary-coded decimal; operations are per-
formed in decimal
(〈address register〉) — The register indirect operation
–(〈address register〉) — Indicates that the operand register points to the memory
(〈address register〉) + — Location of the instruction operand — the optional mode
qualifiers are -, +, (d), and (d,ix)
#xxx or #〈data〉 — Immediate data that follows the instruction word(s)
