TYX is a 65c816 instruction that transfers the value of the Y index register to the X index register. The x flag determines whether 8 or 16 bits are transferred.
The negative flag will then match the most significant bit of the transferred value. The zero flag will indicate whether the transferred value is zero (set if zero).
