software has noticed the status indication. The software clearing
sequence for these flags is automatic. Functions that are normally
performed in response to the status flags also satisfy the conditions of
the clearing sequence.
TDRE and TC flags are normally set when the transmitter is first enabled
(TE set to 1). The TDRE flag indicates there is room in the transmit
queue to store another data character in the TDR. The TIE bit is the local
