The above table shows the relationship between machine language codes and machine language instructions. D 3—D0 show the low-
order 4 bits of the machine language code, and D 9—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 "—."
** cannot be used at M34570M4.
For M34570M4/M8/E8, the SBK and RBK instructions cannot be used.
For M34570MD/ED, the pages which is referred with the TABP instruction (*, **) can be switched with the SBK and RBK instructions.
After executing the SBK instruction, the pages which can be referred with the TABP instruction are 64 to 127. (ex. TABP 0 →TABP 64)
After executing the RBK instruction, the pages which can be referred with the TABP instruction are 0 to 63.
If the SBK instruction is not executed, the pages which can be referred with the TABP instruction are always 0 to 63.
The codes for the second word of a two-word instruction are described below.
