ST10 family

This is the description of ST10 family: This programming manual details the instruction set for the ST10 family of products. The manual is arranged in two sections. Section 1 details the standard instruction set and includes all of the basic instructions. Section 2 details the extension to the instruction set provided by the MAC. The MAC instructions are only available to devices containing the MAC, refer to the datasheet for device-specific information.

In the standard instruction set, addressing modes, instruction execution times, minimum state times and the causes of additional state times are defined. Cross reference tables of instruction mnemonics, hexadecimal opcode, address modes and number of bytes, are provided for the optimization of instruction sequences. Instruction set tables ordered by functional group, can be used to identify the best instruction for a given application. Instruction set tables ordered by hexadecimal opcode can be used to identify specific instructions when reading executable code i.e. during the de-bugging phase. Finally, each instruction is described individually on a page of standard format, using the conventions defined in this manual. For ease of use, the instructions are listed alphabetically. The ATOMIC and EXTended instructions are not available to the ST10X166. The ST10X166 is one of the older members of the ST10 family and does not have the Extended Special Function Register Area. This has been noted throughout the manual where applicable.

The MAC instruction set of the ST10 family is divided into its 5 functional groups: Multiply and Multiply-Accumulate, 32-Bit Arithmetic, Shift, Compare and Transfer Instructions. Two new addressing modes supply the MAC with up to 2 new operands per instruction. Cross reference tables of MAC instruction mnemonics by address mode, and MAC instruction mnemonic by functional code can be used for quick reference. As for the standard instruction set, each instruction has been described individually in a standard format according to defined conventions. For convenience, the instructions are described in alphabetical order.
