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. WebThe TQ interval must be calculated based on the clock and various BRP values, and only the combinations where the TQ interval divides into the bit time by an integer number are possible. Depending on the system …
