PRODUCTION DATA.
The instruction set consists of the original 51 instructions with three formats and seven address modes and additional instructions for the expanded address range. Each instruction can operate on word and byte data. Table 6-1 shows examples of the three types of instruction formats; the address modes are listed in Table 6-2.
FORMAT | EXAMPLE | OPERATION |
---|---|---|
Dual operands, source-destination | ADD R4,R5 | R4 + R5 → R5 |
Single operands, destination only | CALL R8 | PC→ (TOS), R8 → PC |
Relative jump, un/conditional | JNE | Jump-on-equal bit = 0 |
ADDRESS MODE | S(1) | D(1) | SYNTAX | EXAMPLE | OPERATION |
---|---|---|---|---|---|
Register | • | • | MOV Rs,Rd | MOV R10,R11 | R10 → R11 |
Indexed | • | • | MOV X(Rn),Y(Rm) | MOV 2(R5),6(R6) | M(2+R5)→ M(6+R6) |
Symbolic (PC relative) | • | • | MOV EDE,TONI | M(EDE) → M(TONI) | |
