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
