10.3. Description of Interrupt

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
INT2	Self-ID packet error	reports “Bus reset complete” (05h) interrupt.
		Detected logical inverse error while receiving Self-ID packet after
		sending Ping packet in normal transfer mode.
		>Delete receive packet.
		This device has completed Bus reset process and able to perform packet
INT3	Bus reset complete	transfer.
		> All the follows, Bus reset, Tree Identify, and Self Identify, are
		completed by this interrupt information.
		Reset Bus reset in any of the following conditions.
INT4	Bus reset detected	>Detected BUSRESET signal from other node.
		>Received “Bus reset”
		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’
INT5	Isochronous packet receive error (A-ch)	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’).
		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’
INT6	Isochronous packet receive error (B-ch)	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’).
