I would like to be able to "top up" the FIFO when possible so that I
can have more time before the next interupt. Trouble is I am not sure
if I am intepreting the flags correctly, the THRE flag appears to be
set even if just 1 byte has been written, so it is no use for seeing
if the FIFO may be topped up.
