LSI Specification
Rev.1.0 Fujitsu VLSI
Interrupt Interrupt Item Description
INT7 Isochronous cycle too long
Isochronous cycle exceeded specified time.
>Informs only if this node is Cycle master.
INT8 Bus occupancy violation
Node occupied longer time than MAX_DATA_TIME.
>Need to issue “Bus reset”.
INT9 Asynchronous packet received
Received Asynchronous packet addressed to self-node normally, and
stored data at ASYNC receive specific buffer.
INT10 CPIF output header is no 47h (Transmit)
Header byte of source packet output from CPIF at transmitting
MPSG2 -TS is not ‘47h’.
>Valid only when transmitting MPSG2-TS.
INT11 Data length short error Receive packet data length is shorter than data-length of packet header.
INT12 Data length long error
Receive packet data length is longer than data-length of packet header.
>Store only data indicated by data-length value to buffer.
INT13 Packet format error
Detected format error in packet received.
Occurred convention failure of packet format like Reserved range is not
‘0’.
>Delete packet received.
INT14 Header CRC error
Detected CRC error in the header of packet received.
>Delete packet received.
INT15 Data CRC error
Detected CRC error in the data range of packet received.
>Do not delete packet received.
INT16 Asynchronous receive FIFO full
ASYNC receive specific buffer is full.
>Delete following packet received.
INT17 Asynchronous packet send Completed sending Asynchronous packet by issueing instruction.
INT18 Input CGMS or TSCH changed
CGMS or TSCH information input from TSP IC I/F was not consistent
with the souce packet input just before.
INT19 Acknowledge missing
Not returned Acknowledge packet in correspondance with Asynchronous
packet of non-broadcast sent from self-node within specified limit.
INT20 Acknowledge send Completed sending Acknowledge packet.
INT21 Receive EMI or ODD/EVEN changed
Changede EMI data or ODD/EVEN value of received Isochronous
packet.
INT22 First packet received Received the first packet after setting receive ISO channel.
