When initialization is finished, the DCAN module synchronizes itself to the traffic on the CAN bus. It does acceptance filtering on received messages and stores those frames that are accepted into the designated message objects. The application has to update the data of the messages to be transmitted and to enable and request their transmission. The transmission is requested automatically when a matching remote frame is received.
The application may read messages which are received and accepted. Messages that are not read before the next messages is accepted for the same message object will be overwritten.
Messages may be read interrupt-driven or after polling of NewDat.
