Columns indicate the following:
Mnemonic:
Assembler notation of an instruction
~:
Number of instructions
#:
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:
dH is the 8 upper bits of operation description data.
AL and AH must become the contents of AL and AH immediately before the instruction
is executed.
00 becomes 00.
indicates no change.
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.
