CPU32 Instructions
Addressing in the CPU32 is register oriented. Most instructions allow the results of the
specified operation to be placed either in a register or directly in memory. This flexibility
eliminates the need for extra instructions to store register contents in memory. Table 7- 2 lists
the M68000 family addressing modes with cross-references to the MC68000, MC68010,
CPU32, and MC68020. When referring to instructions in the previous sections, refer to Table
7-2 to identify the addressing modes available to the CPU32. Table 7-3 lists the instructions
for the CPU32.
