The Siemens family of 16-bit microcontrollers offers devices that provide various levels of peripheral performance and programmability. This allows the user to equip each specific application with the microcontroller that fits best to the required functionality and performance. The Siemens family concept provides an easy path to upgrade existing applications or to climb tto he next level of performance in order to realize a more sophisticated design. Two major characteristics enable this upgrade path to save and reuse almost all of the engineering efforts that have been made for previous designs:

• All family members are based on the same basic architecture
• All family members execute the same instructions (except for upgrades for new members)

The fact that all members execute the same instructions (almost) saves know-how with respect to the understanding of the controller itself and also with respect to the tools used (assembler, disassembler, compiler, etc.). This instruction set manual provides an easy and direct access to the instructions of the Siemens 16-bit microcontrollers by listing them according to different criteria, and also unloads the technical manuals for the different devices from redundant information. This manual also describes the different addressing mechanisms and the relation between the logical addresses used in a program and the resulting physical addresses. There is also information provided to calculate the execution time for specific instructions depending on the used address locations and also specific exceptions to the standard rules.
