SUB Instruction

Op code  format is of SUB  instruction is

Replace  the three bit code  of the register R from   to obtain the op code of the  required SUB  instruction . op codes  of all  possible SUB instructions  are given.

Notice  that the  change  are made in last  three  positions of the binary cod according  to the codes  of the specified  register.

 Similarly  the readers may  practice of writing op codes  of all  instructions in which  registers  pairs  are used as their  operands.
