Each interrupt items are described below.


Interrupt

Interrupt Item

Description

INT1

Loop detected

Topology is in Loop.
> Need to issue “Bus reset”.

Occurred convention failure like Physical-ID did not count up each
Self-ID packet received during Self Identify process.
> Continues to receive Self-ID packet after reporting interrupt, but

reports “Bus reset complete” (05h) interrupt.

INT2

Self-ID packet error

Detected logical inverse error while receiving Self-ID packet after
sending Ping packet in normal transfer mode.
>Delete receive packet.

INT3

Bus reset complete

This device has completed Bus reset proces s and able to perform packet
transfer.
> All the follows, Bus reset, Tree Identify, and Self Identify, are

completed by this interrupt information.

INT4

Bus reset detected

Reset Bus reset in any of the following conditions.
>Detected BUSRESET signal from other node.
>Received “Bus reset”

INT5

Isochronous packet receive error (A-ch)

The following errors occurred at bridge-Ach during packet receiving.
>Data length value differs from that specified in the format.
>The value of 50/60 range at CIP header is ‘1’ at DV receiving.
>The value of STYPE range at CIP header is other than ‘00000’
or ‘00001’ at DV receiving.
>The value of DBC range at CIP header is discontinuous.
>Header error in CIP header.
>The value of FMT range at CIP header is other than that all owed to
be received at DV-EN, DSS-EN or TS-EN (1Ch-bit10 to 8)
(DV= ‘000000 ’, MPEG2-TS=‘100000 ’, DSS=‘100001 ’).

INT6

Isochronous packet receive error (B-ch)

The following errors occurred at bridge-Bch during packet receiving.
>Data length value differs f rom that specified in the format.
>The value of 50/60 range at CIP header is ‘1’ at DV receiving.
>The value of STYPE range at CIP header is other than ‘00000’
or ‘00001’ at DV receiving.
>The value of DBC range at CIP header is discontinuous.
>Header error in CIP header.
>The value of FMT range at CIP header is other than that allowed to
be received at DV-EN, DSS-EN or TS-EN (1Ch-bit10 to 8)
(DV= ‘000000 ’, MPEG2-TS=‘100000 ’, DSS=‘100001 ’).
