Websition region, and bus contentions). The bus can be driven HIGH or LOW by an active driver, or biased to a known state by external pull up and pull down resistors. These resistors provide the FAILSAFE bias, and the termination configura-tion is also known as a “power termination”. The two bus states are shown in Figure 2. WebTerminal resistors are needed in CAN bus systems because CAN communication flows are two-way. The termination at each end absorbs the CAN signal energy, ensuring that this is not reflected from the cable ends. Such reflections would cause interference and potentially damaged signals.
