Wortlaut
4.1.2.3 Dataset NVRAM block
The Dataset NVRAM block is an array of equally sized data blocks. The application can at one-time access exactly one of this data block. NVM_BLOCK_DATASET type of NVRAM storage consists of the following basic storage objects:
NV Blocks: 1..NvMNvBlockNum
RAM Blocks: 1
ROM Blocks: 0..NvMRomBlockNum
Administrative Blocks: 1 The total number of configured datasets (NV+ROM blocks) must be in the range of 1..255. A specific dataset element is accessed by setting the corresponding index using the API NvM_SetDataIndex. Elements with an index from 0 up to NvMNvBlockNum - 1 represent the NV Blocks, while the ones with an index from NvMNvBlockNum up to NvMNvBlockNum + NvMRomBlockNum - 1 represent the ROM blocks. The NVRAM Block user has to ensure that a valid dataset index is selected before accessing data elements.
