C166 Family Instruction Set
Introduction
1 Introduction
The Siemens family of 16-bit microcontrollers offers devices that provide various levels of peripheral
performance and programmability. This allows to equip each specific application with the
microcontroller that fits best to the required functionality and performance.
Still the Siemens family concept provides an easy path to upgrade existing applications or to climb
the next level of performance in order to realize a subsequent 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 knowhow with respect to
the understanding of the controller itself and also with respect to the used tools (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.
Description Levels
In the following sections the instructions are compiled according to different criteria in order to
provide different levels of precision:
• Cross Reference Tables summarize all instructions in condensed tables
• The Instruction Set Summary groups the individual instructions into functional groups
• The Opcode Table references the instructions by their hexadecimal opcode
• The Instruction Description describes each instruction in full detail
All instructions listed in this manual are executed by the following devices (new derivatives will be
added to this list):
C161V, C161K, C161O, C161RI, C161SI, C161CI, C163, C163F, C164CI, C165, C167, C167CR,
C167SR, C167S, C167CS.
A few instructions (ATOMIC and EXTended instructions) have been added for these devices and
are not recognized by the following devices:
SAB 80C166, SAB 80C166W, SAB 83C166, SAB 83C166W, SAB 88C166, SAB 88C166W.
These differences are noted for each instruction, where applicable.
