Creating DSK Assembler Source FilesUsing the mnemonic fieldThe mnemonic field follows the label field. The mnemonic field must not startin column 1 or it will be interpreted as a label. The mnemonic field can containone of the following opcodes: Machine-instruction mnemonic (such as ADD, MPY, POP) Assembler directive (such as .data, .set, .entry)If you have a label in the first column, a space, colon, or tab must separate themnemonic field (opcode) from the label. For example:.ps 0a00h ; Your code can start here.entrySTART: mar *,AR0lar AR0,#0lacl #03fh ; Turn on all interruptsldp #0Refer to your <strong>TMS320C5x</strong> User’s Guide for syntax specifications on individualopcodes.4-4
Creating DSK Assembler Source FilesUsing the operand fieldTable 4–1. Indirect AddressingThe operand field is a list of operands that follow the mnemonic field. Anoperand can be a constant (see Section 4.2) or a symbol (see Section 4.3).You must separate operands with commas.The assembler allows you to specify that a constant, symbol, or expressionshould be used as an address, an immediate value, or an indirect value. Thefollowing rules apply to the operands of instructions. No prefix — the operand is a well-defined immediate value. Theassembler expects a well-defined immediate value, such as a registersymbol or a constant. This is an example of an instruction that uses operandswithout prefixes:Label: ADD A3The assembler adds the contents of address A3 to the contents of theaccumulator. * prefix — the operand is a register indirect address. If you use the *sign as a prefix, the assembler treats the operand as an indirect address;that is, it uses the operand as an address. For example:Label: ADD *+,AR3The following symbols are used in indirect addressing, including bitreversed(BR) addressing. A * indicates that the contents of AR are usedas the data memory address plus the functions indicated.Operand*Additional Functions*+ Incremented after the access*– Decremented after the access*0+ The contents of INDX are added to AR after the access*0– The contents of INDX are subtracted from AR after the access*BRO+*BRO–The contents of AR0 are added to AR with reverse carry (rc) propagationafter the accessThe contents of AR0 are subtracted from AR with reverse carry(rc) propagation after the accessFor more information on indirect addressing and bit-reversed addressing,refer to Memory Addressing Modes in the <strong>TMS320C5x</strong> User’s Guide.Using the DSK Assembler4-5
