> or Tx.

> To correct it I have added the configuration for these values to this patch. In
> addition I did some minor clean-up to just add a local pointer for the vector
> map instead of dereferencing it based off of the index repeatedly. In my
> opinion this makes the resultant code a bit more readable and saves us a few
> characters.
