TMS320F28035: eCAN responding to a remote request without auto answer

Part Number: TMS320F28035


Is it possible to respond to a remote request without using the auto answer feature? I haven't found any example or description of this, so before I experiment, perhaps someone can tell me if its possible.  I want to use one mailbox (and one id).  The process would be something like

1. CAN remote request frame is received, which generates an interrupt

2 interrupt handler generates new data

3. data is written to the mailbox and transmitted

    Carl,

        The sequence you describe is applicable for  "normal" data frames. The reason you would want to use remote frames is to be able to automatically respond to them. Perhaps I am missing something here, but it looks like you do not need remote-frames in your application. Are you asking if a remote-frame is received by a mailbox (with a matching ID, but not with auto-answer enabled), if it would be received and an interrupt generated? If so, why would you want to use remote-frames in the first place? Why not a data frame?
