rUnCc Detween ite betweell data and addresses.) 22. List the hexadecimal code for the following program (hand assemble it). Hex Address Label Instruction 100 101 102 103 LOAD A ADD ONE JUMP S1 ADD ONE S2

Solution

There are already defined hex codes for each operation which we are going to use below:

LOAD A: 3A, 23, 00 //loading A reg to mem location 0023 as mentioned by label A at 108H
   //3A is the hex code for loading A reg to accumulator (00111010)

ADD ONE: 86, 01, 00 //86 is the hex code for loading a memory location content to accumulator (10000110)

JUMP S1: C3, 06, 01 //C3 is the hex code for jump and S1 label indicates 106H (11000011)

ADD ONE: 86, 01, 00

STORE A: 32, 23, 00 //32 is the hex code for storing contents of acc to mem location which is 0023H(00110010)

HALT: 76H

ADD A: 87H //instruction is 100000sss where sss indicates which reg to use i.e. 111 for A reg

JUMP S2: C3, 03, 01 //S2 indicates 103H
