This reads a bit strange at first. Also it is helpful for later to state
that this does not make a difference in practise, so how about:

Use define from the 32-bit register description UARTMODIR_* instead of
UARTMODEM_*. The value is the same, so there is no functional change.

Otherwise looks good to me:
