Devices in the Motorola M68HC16 modular microcontroller family are built up from standard modules that interface via a common internal bus. Modularity facilitates rapid development of devices tailored for specific applications. The standard central processing unit in the M68HC16 family is the 16-bit CPU16 module. Both the CPU16 programming model and the CPU16 instruction set are designed for compatibility with the M68HC11 CPU, and M68HC11 applications can be ported to the CPU16 with moderate effort. However, because the CPU16 has additional capabilities, the functions of certain M68HC11 instructions have been modified and some M68HC11 CPU instructions have been replaced by instructions specific to the CPU16. In addition, the M68HC11 CPU and CPU16 manage interrupts differently.
