4.6 Instruction Set
The CPU16 instruction set is based on that of the M68HC11, but the opcode map has been rearranged
to maximize performance with a 16-bit data bus. All M68HC11 instructions are supported by the CPU16,
although they may be executed differently. Most M68HC11 code runs on the CPU16 following reassem-
bly. However, take into account changed instruction times, the interrupt mask, and the new interrupt
stack frame.
The CPU16 has a full range of 16-bit arithmetic and logic instructions, including signed and unsigned
multiplication and division. New instructions have been added to support extended addressing and dig-
ital signal processing.
Table 33 is a quick reference to the entire CPU16 instruction set. Because it is only affected by a few
instructions, the LSB of the condition code register is not shown in the table. Instructions that affect the
interrupt mask and PK field are noted. Table 34 provides a key to the table nomenclature.
