'''''TXS (Transfer X Index to Stack Pointer)''''' transfers the value in the [[X Index Register|X index]] to the [[Stack Pointer Register|stack pointer]]. The reverse of this opcode is [[TSX]].

==Operation==
This pseudo C code shows how the TXS opcode functions when it is executed.

 unsigned src = X;             // Load the value of the X index as an unsigned byte.
 SET_NEGATIVE(src);            // Sets the [[Negative Flag]] equal to the 7th bit.
 SET_ZERO(src);                // Sets the [[Zero Flag]] if the Operand is $#00, otherwise clears it.
 S = (src);                    // Stores the value of the X index into the stack pointer.
