Bus biasing can be normal biasing, active in normal mode and inactive in low-power mode. Automatic voltage biasing is where the bus is active in normal mode but is controlled by the voltage between CANH and CANL in lower power modes. See Figure Figure 9-3 for the state diagram on how the TCAN4550-Q1 performs automatic biasing. Figure Figure 9-4 provides the bus biasing based upon the mode of operation.
