|
|
* @brief Data definitions for the Cortex-M3 Non-Volatile Memory data storage
|
|
* system.
|
|
*
|
|
* This header defines all of the data sets in the NVM data storage. Each
|
|
* piece of data in NVM storage uses an offset to indicate where the data
|
|
* lives and a size to indicate the size of that data. Both the offset
|
|
* and size are defined in bytes and must be a mupltiple of 16bits. The
|
|
* offset is from the start of an NVM page, defined by NVM_LEFT_PAGE and
|
|
* NVM_RIGHT_PAGE. The offset and size must be below the maximum size
|
|
* of NVM storage as defined by NVM_DATA_SIZE_B. All NVM data must start
|
|
* above NVM_MGMT_SIZE_B, since this is where the management bytes live.
|
|
*
|
|
* @note This file is not directly used by the nvm.c or nvm.h files. This
|
|
* file is intended to be a convenient place to define all data that
|
|
* lives in NVM so it can be seen together in one group. nvm.h includes
|
|
* this file which means any code that includes nvm.h to call the read
|
|
* and write functions also has access to these defines.
