4.6 Instruction Set
The CPU16 instruction set is based on that of the M68HC11, but the opcode map has been rear-
ranged 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 reassembly. 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 un-
signed multiplication and division. New instructions have been added to support extended address-
ing and digital signal processing.
Table 35 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 36 provides a key to the table nomenclature.
