Indicates that the Receive Output Buffer has a newly processed
octet in it. The DSP must read this octet before starting the next
processing session, otherwise it might be lost.
The transmit buffer is full.
The transmit buffer is empty. The current time slot in the
Transmit Input Buffer has been fully processed by the HDLCU.
The Transmit Input buffer is ready to receive the next octet of
the message by the DSP.
Note: The DSP must put a new octet into the buffer before
