A TNS Instruction Lists
This appendix provides two tables that list all instructions in the TNS instruction set
with their mnemonics and opcodes, first in alphabetic order by mnemonic and then
grouped by type of instruction. The tables are:
Table A-1, Alphabetic List of Instructions, on page A-1
Table A-2, Categorized List of Instructions, on page A-9
For some instructions, the six-digit opcode notation used in Table A-1 and Table A-2
cannot give complete information about the opcode. For instance, the distinctions
between QUP and QDWN, ORRI and ORLI, and LWP and LBP cannot be clearly
shown. For complete binary coding information, refer to the entries for these
instructions in Appendix B, TNS Instruction Binary Coding.
As indicated in the footnotes for these tables, a single asterisk (*) following an
instruction description denotes a privileged instruction and a double asterisk (**)
denotes an instruction intended only for operating system use.
