We are using the TJA1100 as a PHY with MPC5746C in an Automotive project.
I need to test the behavior of the cable errors: ( Short/open circuit) of the two wires of the cable on the link status.
I mean: what will be the link status once I forced a cable error on the wires ?
shall it the link be in down stats or what ?
Yes, the TJA1100 provides a "cable test" feature. Details how it can be used can be found in section 6.10.2 of the data sheet.
If a cable problem happens during normal operations, it will be signaled by LINK_UP status bit that will changed from 1 to 0. LINK_STATUS_FAIL interrupt is generated by the PHY in such a case.
Thanks for your reply.
Still I have some points to be clarified:
Could you please clarify the questions in the same arrangement
