Mul-table challenge

I was just coding another multiplication and once again I had to code a mul-table generator. Somehow I felt like doing it as small as possible and settle this forever. The routine should create:

- function: int((x*x)/4)
- x = 0 to 511
- two tables: 512 low bytes and 512 high bytes
- no dependencies on previous zeropage or register settings

So far I managed to do it in 54 bytes (RTS not included), is anyone able to do a smaller version?

EDIT:

53 bytes now :)

RUN clears all variables. You can circumvent that with GOTO <first_line> tho.
