correct. any offset  that is zero whether 0,X or ,X for indexing should 
genereate a two byte operation. the first being the ld opcode and the second 
byte fetched is the post byte opcode. 8 and 16 bit offsets require more bytes 
loaded and more machine cycles. 8 bit offsets require another byte to be 
loaded and a 16 bit offset requires another 2 bytes to be loaded.
