HDLC2 Message Type Identifier
This READ ONLY bit indicates the type of data link message
received by Receive HDLC 2 Controller. Two types of data link mes-
sages are supported within the XRT86VL38 device: Message Ori-
ented 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
message is received

Transmit HDLC2 Controller Start of Transmission (TxSOT)
Interrupt Status
This Reset-Upon-Read bit indicates whether or not the “Transmit
HDLC2 Controller Start of Transmission (TxSOT) “Interrupt has
occurred since the last read of this register. Transmit HDLC2 Con-
troller will declare this interrupt when it has started to transmit a data
link message. For sending large HDLC messages, start loading the
next available buffer once this interrupt is detected.
0 = Transmit HDLC2 Controller Start of Transmission (TxSOT) inter-
rupt has not occurred since the last read of this register
1 = Transmit HDLC2 Controller Start of Transmission interrupt
(TxSOT) has occurred since the last read of this register.

Receive HDLC2 Controller Start of Reception (RxSOT) Interrupt
Status
This Reset-Upon-Read bit indicates whether or not the Receive
HDLC2 Controller Start of Reception (RxSOT) interrupt has
occurred since the last read of this register. Receive HDLC2 Con-
troller will declare this interrupt when it has started to receive a data
link message.
0 = Receive HDLC2 Controller Start of Reception (RxSOT) interrupt
has not occurred since the last read of this register
1 = Receive HDLC2 Controller Start of Reception (RxSOT) interrupt
has occurred since the last read of this register

Transmit HDLC2 Controller End of Transmission (TxEOT) Inter-
rupt Status
This Reset-Upon-Read bit indicates whether or not the Transmit
HDLC2 Controller End of Transmission (TxEOT) Interrupt has
occurred since the last read of this register. Transmit HDLC2 Con-
troller will declare this interrupt when it has completed its transmis-
sion 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 HDLC2 Controller End of Transmission (TxEOT) inter-
rupt has not occurred since the last read of this register
1 = Transmit HDLC2 Controller End of Transmission (TxEOT) inter-
rupt has occurred since the last read of this register
