Description
Operation
Affected flag(s)
Move the ROM code (last page) to TBLH and data memory
The low byte of ROM code (last page) addressed by the table pointer
(TBLP) is moved to the data memory and the high byte transferred to
TBLH directly.
[m] ¬ ROM code (low byte)
TBLH ¬ ROM code (high byte)
Logical XOR accumulator with data memory
Data in the accumulator and the indicated data memory performs a
bitwise logical Exclusive_OR operation and the result is stored in the ac-
cumulator.
ACC ¬ ACC ²XOR² [m]
Logical XOR data memory with accumulator
Data in the indicated data memory and the accumulator perform a
bitwise logical Exclusive_OR operation. The result is stored in the data
memory. The zero flag is affected.
[m] ¬ ACC ²XOR² [m]
Logical XOR immediate data to accumulator
Data in the accumulator and the specified data perform a bitwise logical
Exclusive_OR operation. The result is stored in the accumulator. The
zero flag is affected.
ACC ¬ ACC ²XOR² x
