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 representa-
tion 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 M34554M8.
• * cannot be used after the SBK instruction is executed in the M34554MC.
• A page referred by the TABP instruction can be switched by the SBK and RBK instructions in the
M34554MC/ED.
• The pages which can be referred by the TABP instruction after the SBK instruction is executed are 64 to
95 in the M34554MC.
• The pages which can be referred by the TABP instruction after the SBK instruction is executed are 64 to
127 in the M34554ED.
(Ex. TABP 0 → TABP 64)
• 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.
