floating-point operations with the MC68881 and MC68882 floating-point co-
The 18 addressing modes, shown in Table 1-1, include nine basic types:
The register indirect addressing modes can also postincrement, predecre-

Seven basic data types are supported:
In addition, the instruction set supports operations on other data types such
processors as well as specialized user-defined data types and functions.

has index and offset capabilities. As in the MC68020, both modes are ex-
addressing modes, many instructions implicitly specify the use of the con-
dition code register, stack pointer, and/or program counter.
The instructions in the MC68030 instruction set are listed in Table 1-2. The
