5 LIN Transceiver Special Functions

With most modern LIN transceivers, there are special functions that help with specific application needs. Most of the features listed are for systems that focus on low power consumption. The descriptions of these features are specific to TI devices, but can be generalized for all transceivers across the industry. Naming conventions of the modes and specific internal function of the transceiver in the modes and features, can differ for devices from other companies.
