A feature of the CAN protocol is that the bit rate, bit sample point and number of samples in a bit period are user programmable. This gives the user the freedom to optimize the performance of the network for his given application. During this optimization process the user has to be aware of the relationship between the bit timing parameters, the reference oscillator tolerance and the various signal propagation delays in the system.

This document describes the bit timing settings using the Philips SJA1000 CAN controller.
