MX Foundation allows filtering and async event to be performed on CAN IDs.

In acquisition, by default, every possible message ID can be received. If acquisition filtering is used, with mxfCanBusRxAcqMsgSelectSet(), 256 different message IDs can be received. Only messages that the ID is in the list of selected IDs will be returned to the application. The acquisition filtering shares the same 256 possible filter with NV storage and Rx Msg async event.

In sampling, by default, 256 different message ID can be received. Each time a new message ID is received, it takes one of the 256 available spots. When filtering in sampling is used, with mxfCanBusRxSamplingMsgSelectSet(), still 256 different message IDs can be received but only messages that the ID is in the list of selected IDs will be returned to the application.

In transmission, a maximum of 256 buffers can be allocated on a channel.
