4.8 Comparison of CPU16 and M68HC11 CPU Instruction Sets
MC68HC16Y3/916Y3
USER’S MANUAL
Most M68HC11 CPU instructions are a source-code compatible subset of the CPU16
instruction set. However, certain M68HC11 CPU instructions have been replaced by
functionally equivalent CPU16 instructions, and some CPU16 instructions with the
same mnemonics as M68HC11 CPU instructions operate differently.
Table 4-4 shows M68HC11 CPU instructions that either have been replaced by
CPU16 instructions or that operate differently on the CPU16. Replacement instruc-
tions are not identical to M68HC11 CPU instructions. M68HC11 code must be altered
to establish proper preconditions.
All CPU16 instruction execution times differ from those of the M68HC11. Motorola
Programming Note M68HC16PN01/D, Transporting M68HC11 Code to M68HC16
Devices , contains detailed information about differences between the two instruction
sets. Refer to the CPU16 Reference Manual (CPU16RM/AD) for further details about
CPU operations.
