The above table shows the relationship between machine language codes and machine language instructions. D3–D0 show the low-order
4 bits of the machine language code, and D9–D4 show the high-order 6 bits of the machine language code. The hexadecimal
representation of the code is also provided. There are one-word instructions and two-word instructions, but only the first word of each
instruction is shown. Do not use code marked “–.”
The codes for the second word of a two-word instruction are
described below.
