indicator, this bit will not be set (nor will produce an
interrupt request) if one or two characters are still
remaining in RHRB, following data reception. Hence, it is
possible that the last two characters in a string of data
(being received) could be lost due to this phenomenon.

Note:
If this bit is configured to reflect the FFULLA
indicator, this bit will not be set (nor will produce an
interrupt request) if one or two characters are still
remaining in RHRA, following data reception. Hence, it is
possible that the last two characters in a string of data
(being received) could be lost due to this phenomenon.
Therefore, the user is advised to read RHRA until empty.
