MC68EC030 Datasheet, PDF (10/36 Pages) Motorola, Inc – Second-Generation 32-Bit Enhanced Embedded Controller

Freescale Semiconductor, Inc.
INSTRUCTION SET OVERVIEW
The MC68EC030 instruction set is listed in Table 2. Each instruction, with few exceptions, operates on
bytes, words, and long words, and most instructions can use any of the 18 addressing modes. The
MC68EC030 is upward source- and object-level code compatible with the M68000 Family because it
supports all instructions of previous family members.
