HDLC3 Message Type Identifier
This READ ONLY bit indicates the type of data link message received
by Receive HDLC 3 Controller. Two types of data link messages are
supported within the XRT86VL34 device: Message Oriented Signaling
(MOS) or Bit-Oriented Signalling (BOS).
0 = Indicates Bit-Oriented Signaling (BOS) type data link message is
received
1 = Indicates Message Oriented Signaling (MOS) type data link mes-
sage is received

Transmit HDLC3 Controller Start of Transmission (TxSOT) Inter-
rupt Status
This Reset-Upon-Read bit indicates whether or not the “Transmit
HDLC3 Controller Start of Transmission (TxSOT) “Interrupt has
occurred since the last read of this register. Transmit HDLC3 Controller
will declare this interrupt when it has started to transmit a data link mes-
sage. For sending large HDLC messages, start loading the next avail-
able buffer once this interrupt is detected.
0 = Transmit HDLC3 Controller Start of Transmission (TxSOT) interrupt
has not occurred since the last read of this register
1 = Transmit HDLC3 Controller Start of Transmission interrupt (TxSOT)
has occurred since the last read of this register.

0
Receive HDLC3 Controller Start of Reception (RxSOT) Interrupt
Status
This Reset-Upon-Read bit indicates whether or not the Receive
HDLC3 Controller Start of Reception (RxSOT) interrupt has occurred
since the last read of this register. Receive HDLC3 Controller will
declare this interrupt when it has started to receive a data link mes-
sage.
0 = Receive HDLC3 Controller Start of Reception (RxSOT) interrupt
has not occurred since the last read of this register
1 = Receive HDLC3 Controller Start of Reception (RxSOT) interrupt
has occurred since the last read of this register

0
Transmit HDLC3 Controller End of Transmission (TxEOT) Interrupt
Status
This Reset-Upon-Read bit indicates whether or not the Transmit
HDLC3 Controller End of Transmission (TxEOT) Interrupt has occurred
since the last read of this register. Transmit HDLC3 Controller will
declare this interrupt when it has completed its transmission of a data
link message. For sending large HDLC messages, it is critical to load
the next available buffer before this interrupt occurs.
0 = Transmit HDLC3 Controller End of Transmission (TxEOT) interrupt
has not occurred since the last read of this register
1 = Transmit HDLC3 Controller End of Transmission (TxEOT) interrupt
has occurred since the last read of this register
