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 changed content of the TL, TH and AH when instruction is executed. Symbols in the
column indicate the following:
“-”
indicates no change.
dH is the 8 upper bits of data described in the column “operation”.
AL and AH must become the contents of AL and AH preceding the instruction executed.
00 becomes 00.
N, Z, V, C:
Flags of the condition code register. 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.
