Each 00016 * piece of data in NVM storage uses an offset to indicate where the data 00017 * lives and a size to indicate the size of that data. Both the offset 00018 * and size are defined in bytes and must be a mupltiple of 16bits. The 00019 * offset is from the start of an NVM page, defined by NVM_LEFT_PAGE and 00020 * NVM_RIGHT_PAGE. The offset and size must be below the maximum size 00021 * of NVM storage as defined by NVM_DATA_SIZE_B. All NVM data must start 00022 * above NVM_MGMT_SIZE_B, since this is where the management bytes live. 00023 * 00024 * @note This file is not directly used by the nvm.c or nvm.h files. This 00025 * file is intended to be a convenient place to define all data that 00026 * lives in NVM so it can be seen together in one group. nvm.h includes 00027 * this file which means any code that includes nvm.h to call the read 00028 * and write functions also has access to these defines. 00029 *@{ 00030 */ 00031 00032 #ifndef __NVM_DEF_H__ 00033 #define __NVM_DEF_H__ 00034 00035 //The bottom 64 bytes of NVM storage is allocated to radio calibration 00036 //values.
