PCAN_BUSOFF_AUTORESET together with PCAN_RECEIVE_EVENT

I am troubleshooting an issue where we are not receiving the receive signal even though data is available to be read from the channel.
I have a question about the combination of these two options that wasn't clear to me after reviewing the documentation.
The PCAN_RECEIVE_EVENT has this information:

Note that when you need to reinitialize a PCAN-Channel, you will need to set the event again each time after initializing the channel, since the event will have again its default value of 0 after initialization.

Would an autoreset of the bus cause the channel to be reinitialized (disabling the signalling behavior of the previously prepared receive event)?

Hello,

This is more a question about the PCAN-Basic Api. I will move this post to the corresponding place.

Would an autoreset of the bus cause the channel to be reinitialized (disabling the signalling behavior of the previously prepared receive event)?

No. When you configure the PCAN_BUSOFF_AUTORESET parameter, the hardware reset occurs when a bus off status is detected but the current configuration like filters and event are maintained. The information you have quoted is referring to the case when you re-initialize a channel (calling first CAN_Uninitialize, followed by CAN_Initialize). In this case, the configuration made to the channel is lost and you need to call CAN_SetValue to set the read event again.

Perfect. Thanks!
