Write the assembler In assembly language . Translate the assembler Into octal. Use the loader to read the assembler. Use the assembler to read an assembly language version of Itself.
Mode 2 with PC simply causes an operand to be selected from the store line whose address Is given by PC and PC Is Incremented by 2. However. when an Instruction containing this model register combination Is being executed . PC Is the address of the next 'Instruction' which Is therefore treated as a constant. Consider. for example. the Instruction 062702 000005 which achieves the action R2 <= R2 + 5 and Is In effect a 32-blt Instruction . This mode with PC Is called Immediate mode. Mode 3 with PC again results In what Is In effect an extended Instruction.
1. 6 Address modes 2. 3. 6 and 7 with PC Any addressing mode can be used with PC . the program counter . but the effects of using 2 . 3. 6 and 7 with PC are the most Interesting and are given special names . The other modes are rarely. If ever. used with PC. Mode 2 with PC simply causes an operand to be selected from the store line whose address Is given by PC and PC Is Incremented by 2.
