IX - EXTERNAL REGISTERS (continued)
G0
A2/0
C6/1
A, E, S1/S4 bits received twice consecutively. Case of S0 = 1 S1 = 0.
Bit0/5 are not Significant when S0 = 0, S1 = 1.
IX.5.2 - Receive Command / Indicate Interrupt when TSV = 1
Time Stamping validated (bit of GCR Register)
These two words are located in the Command/Indicate interrupt queue.
First word see definition above.
T0/15: binary counter value when a new primitive is occured.
IX.6 - Receive Monitor Interrupt
IX.6.1 - Receive Monitor Interrupt when TSV = 0
TSV : Time Stamping not Validated (bit of GCR Register)
These two words are transferred into the Monitor interrupt queue ; IQSR Register indicates the size of this
interrupt queue located in the external memory.

: This bit defines one of two GCI y (DIN4/DOUT4 or DIN5/DOUT5).
: GCI Channel 0 to 7 belonging to GCI 0 or GCI 1.
: New Primitive received twice consecutively. Case of S0=S1=0.
: New Status.
: G0 = 0, GCI 0 corresponding to DIN4 input and DOUT4 output.
: Last byte
: First byte
: Abort

G0 = 0, GCI0 (DIN4/DOUT4) is the source.
G0 = 1, GCI1 (DIN5/DOUT5) is the source.
Before writing the features of event in the external memory the Interrupt Controller reads the
NS bit :
if NS = 0, the Interrupt Controller stores two new bytes M1/8 and M11/18 then puts NS bit at ‘1’
when it writes the status of these two bytes which has been received.
if NS = 1, the Interrupt Controller puts ICOV bit at ‘1’ to generate an interrupt (IR Register).
G0 = 1, GCI 1 corresponding to DIN5 input and DOUT5 output.
L=1, two cases:
if ODD = 1, the following word of the Interrupt Queue contains the Last byte of message
if ODD =0, the previous word of the Interrupt Queue (concerning this channel) contains the Last
byte of message.
L = 0, the following word and the previous word does not contains the Last byte of message.
F=1, the following word contains the First byte of message.
F=0, the following word does not contain the First byte of message.
A=1, Received message has been aborted.
