STR - Store Register to Register/Address

A 16 bit move from register to register or register to address.

Odd registers indicate register to address. The equivalent even register is used.

|  D   6  | dr   sr | literal/address high byte | literal/address low byte |

• dr = Destination Register

NOTE: sr and dr are opposite to 5x instructions, possibly because this is an opposite instruction to XFR
