10 / 36 page  1 0 MC68EC030 TECHNICAL DATA MOTOROLA 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. Table 2.
