s INSTRUCTIONS (136 INSTRUCTIONS)

Execution instructions can be divided into the following four groups:

• Transfer

• Arithmetic operation

• Branch

•Others

Table 1 lists symbols used for notation of instructions.

Table 1

Instruction Symbols

Columns indicate the following:

Mnemonic: Assembler notation of an instruction

The number of instructions

The number of bytes

Operation:

Operation of an instruction

TL, TH, AH:

A content change when each of the TL, TH, and AH instructions is executed. Symbols in

the column indicate the following:

•

“–” indicates no change.

• 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.

N, Z, V, C:

An instruction of which the corresponding flag will change. If + is written in this column,

the relevant instruction will change its corresponding flag.

OP code:

Code of an instruction. If an instruction is more than one code, it is written according to

the following rule:

Example: 48 to 4F

← This indicates 48, 49, ... 4F.

(Whether its length is 8 or 16 bits is determined by the instruction in use.)

((

× ))

The address indicated by the contents of

× is the target of accessing.

(Whether its length is 8 or 16 bits is determined by the instruction in use.)
