MICROPROCESSOR INSTRUCTION REFERENCE->MOV

MOV    Move Byte Variable:  Move <destination byte>,<source byte>

The byte variable indicated by the second operand is copied into the location specified by the first operand.  No other register or flag is affected.

where Ri is R0 or R1 and Rn is R0 - R7.     (MOV A,ACC is not allowed)


MOV    Move Bit Data: Move <destination byte>,<source byte>

The Boolean variable indicated by the second operand is copied into the location specified by the first operand.  One of the operands must be the carry flag, the other may be any directly addressable bit.  No other register or flag is affected.
