[12] Receive Event Time out (E_RxTO)
0 = A promised time is not elapsed during receiving.
1 = Valid data in a promised time
NOTE: A promised time is determined according to
WL (Word Length): Promised time = 4*WL + 12)
[13] Auto Baud Rate Detection Done (AUBDDN)
0 = Before AutoBaud Rate Detection
1 = After AutoBaud Rate Detection
[14] Data Set Ready (DSR)
0 = DSR pin goes High
1 = DSR pin goes Low
[15] Clear To Send (CTS)
0 = CTS pin goes High
1 = CTS pin goes Low
[16] CTS event occured (E_CTS)
0 = CTS pin has changed.
1 = CTS pin keep it's level
[17] Transmitter Idle (TI)
0 = Transmit is in progress.
1 = Transmitter is in idle; no data for Tx
[18] Transmit Holding Register Empty (THE)
0 = TxFIFO at trigger level or tranmit holding register is not empty.
