Transmitter Busy Flag.
0 - Transmitter is idle, or disabled, or an abort is being
transmitted.
1 - Transmit logic is currently transmitting a frame.
Receiver In Frame.
0 - Receiver is in preamble/start flag or is in hunt mode.
1 - Receiver is in a frame.
Receiver Synchronized Flag.
0 - Receiver is in hunt mode.
1 - Receiver logic is synchronized within the incoming
data.
End of Frame.
0 - Current frame is not completed.
1 - The word in the receive buffer contains the last byte of
data within the frame. When the last word in the current
frame is read this bit is cleared.
