Codify the remaining code instructions by specifying the different fields and the resulting machine code

Guidelines:

The opcode and the @mode should be given in binary.
The offset, the value and the machine code must be given in hexadecimal. Do not include the H of hexadecimal in the answer
Put just a slash '/' in the unneeded fields.
Do not include any spaces
