Shared Drivers
Logical device drivers support the shared mode that means that more components can be
put together to provide one instance of API. You can access each component instance
through the API of the shared component. A driver device data structure is used for
resolution which peripheral instance shall be accessed. Currently there are three
components that support shared mode: Serial_LDD, CAN_LDD and Ethernet_LDD.
Low Power Features
Logical device drivers in conjunction with processor component implement low power
features of a target microcontroller. Each LDD component define two methods related to
the low power capability – SetOperationMode() and GetDriverState(). For
more details, refer to the documentation of components.
