Description: MOV copies the value of operand2 into operand1. The value of operand2 is not affected. Both operand1 and operand2 must be in Internal RAM. No flags are affected unless the instruction is moving the value of a bit into the carry bit in which case the carry bit is affected or unless the instruction is moving a value into the PSW register (which contains all the program flags).

** Note: In the case of "MOV iram addr,iram addr", the operand bytes of the instruction are stored in reverse order. That is, the instruction consisting of the bytes 0x85, 0x20, 0x50 means "Move the contents of Internal RAM location 0x20 to Internal RAM location 0x50" whereas the opposite would be generally presumed.
