* If using non-RTR messages for information request messages (IRM), the RTR bit = 0, DLC bit field = 0, and bit 3 of the IRM ID = 1. Also, bit 3 of the output message ID = 0.
If using RTR messages for IRMs, the RTR bit = 1, DLC bit field = number of bytes in corresponding output message, and bit three of the IRM ID = x (don’t care), also, bit 3 of the
output message = x (don’t care).
** User-defined IRM IDs must be different from input message IDs to avoid message contention between the corresponding output message and the input message.
