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.

• **(SBK and RBK instructions) cannot be used in the M3455AG8.
• * cannot be used after the SBK instruction executed in the M3455AGC.
• A page referred by the TABP instruction can be switched by the SBK and RBK instructions in
the M3455AGC.
• The pages which can be referred by the TABP instruction after the SBK instruction is executed
are 64 to 95 in the M3455AGC.
• The pages which can be referred by the TABP instruction after the RBK instruction is executed
are 0 to 63.
• When the SBK instruction is not used, the pages which can be referred by the TABP instruction
are 0 to 63.
