http://www.bittiming.can-wiki.info/ WebThe bit timing for each node in a CAN system is derived from the reference frequency (fOSC) of its node. This creates a situation where phase shifting and oscillator drift will occur between nodes due to less than ideal oscillator tolerances between the nodes.

WebThe BxCAN supports three test modes: • In Silent mode, the BxCAN is able to receive valid frames, but it sends only recessive bits on the CAN bus and it cannot start a transmission. Silent mode can be used to analyze traffic on a CAN bus without affecting it by the transmission of dominant bits. • In Loop Back mode, the BxCAN treats its own
