Execution instructions can be divided into the following four groups:
• Transfer
• Arithmetic operation
• Branch
• Others
Columns indicate the following:

Accumulator A (Whether its length is 8 or 16 bits is determined by the instruction in use.)
Upper 8 bits of accumulator A (8 bits)
Lower 8 bits of accumulator A (8 bits)
Temporary accumulator T (Whether its length is 8 or 16 bits is determined by the instruction in use.)

A content change when each of the TL, TH, and AH instructions is executed. Symbols in
the column indicate the following:
An instruction of which the corresponding flag will change. If + is written in this column,
the relevant instruction will change its corresponding flag.
Code of an instruction. If an instruction is more than one code, it is written according to
the following rule:
Example: 48 to 4F
•
• dH is the 8 upper bits of operation description data.
• AL and AH must become the contents of AL and AH prior to the instruction executed.
• 00 becomes 00.
