Rev. 1.00 27 December 4, 2001
Note: ²x² 8-bit immediate data
²m² 7-bit data memory address
²A² accumulator
²i² 0~7 number of bits
²addr² 10-bit program memory address
²Ö² Flag(s) is affected ²- ² Flag(s) is not affected
²*² Flag(s) may be affected by the execution status
²**² 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.
