WebCAN network has its own clock generator, usually a quartz oscillator. The timing parameter of the bit time (i.e. the reciprocal of the bit rate) can be conﬁgured individually for each CAN node, cre-ating a common bit rate even though the CAN nodes’ oscillator periods (fosc) may be different. Webfor acknowledge, called the Arbitration Phase; the new data bit time may be used for the main part of the frames, called the Data Phase. The data bit time may be shorter than the nominal bit time in order to speed up frame transmission.
