Bit 3 (CCTS: CTS Line Level Change): Indicates whether or not the CTS line level has
changed. This bit is cleared when 1 is written to this bit position.
Bit 2 (CDCD: DCD Line Level Change): Indicates whether or not the DCD line level has
changed. This bit is cleared when 1 is written to this bit position.
Bit 1 (BRKD/ABTD: Break Start Detection/Abort Detection): Indicates the detection of a
break start (space state) in asynchronous mode or an abort in bit synchronous HDLC mode. This
bit is cleared when 1 is written to this bit position.
Bit 0 (BRKE/IDLD: Break End Detection/Idle Start Detection): Indicates the detection of a
break end in asynchronous mode, or an idle start in bit synchronous mode. This bit is cleared
when 1 is written to this bit position.
