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.

 

 

 

 

 

 

 

 

 

 

 

Detected format error in packet received.

 

 

INT13

Packet format error

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.
