Non Volatile RAM Manager: The NvM module manages, reads, and writes data to a nonvolatile memory (Ea or Fee). At system start and at shutdown, it synchronizes the data in the RAM areas of the application. The module provides services such as saving of redundant blocks for a higher level of data protection. Since AUTOSAR 4.0.3, the Rte also provides a simpler and more flexible interface to Nv data (NvDataInterfaces).
