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.
