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 “–.”
• *, **, and *** cannot be used in the M34571G4.
The codes for the second word of a two-word instruction are _{• ** and *** cannot be used in the M34571G6.}
described below.

the SBK and RBK instructions in the M34571GD.
The pages which can be referred by the TABP instruction after
the RBK instruction is executed are 0 to 63.
The pages which can be referred by the TABP instruction after
the SBK instruction is executed are 64 to 127 (Ex. TABP 0
TABP 64).
