5.1.10 Glitch-Free Power Up and Power Down

This feature provides for hot-plugging onto a powered bus without disturbing the network. The TI driver and receiver pins are passively pulled high internally while the bus pins are biased internally to a high-impedance recessive state. This provides for a power up into a known recessive condition without disturbing ongoing bus communication.
