Note:
If this bit is configured to reflect the FFULLB indicator, this
bit will not be set (nor will produce an interrupt request) if
oneortwocharactersarestillremaininginRHRB,following
data reception. Hence, it is possible that the last two char-
acters in a string of data (being received) could be lost due
to this phenomenon.
