: Flag(s) is affected
: Flag(s) is not affected
*: Flag(s) may be affected by the execution status
**: For the old version of the E.V. chip, the zero flag (Z) can be affected by executing the
MOV A,[M] instruction.
For the new version of the E.V. chip, the zero flag cannot be changed by executing the
MOV A,[M] instruction.
