IAR 7.50;  KW40Z_Connectivity_Software_1.0.1 (KSDK_1.3.0)


What is the usage of  reserved[42] data, what module use this data ?

For backward compatibility with what ?


typedef PACKED_STRUCT hardwareParameters_tag
  uint8_t  reserved[42];             /* for backward compatibillity */
    uint8_t  ieee_802_15_4_address[8]; /* IEEE 802.15.4 MAC address */
    uint8_t  bluetooth_address[6];     /* Bluetooth address */
    uint32_t xtalTrim;                 /* KW4x only */
    uint32_t edCalibrationOffset;      /* KW01 ED offset */
    uint32_t pllFStepOffset;           /* KW01 fine tune pll */
    uint32_t gInternalStorageAddr;     /* The start address of the internal storage used for OTA update.
                                          A value of 0xFFFFFFFF means that the External storage is used. */


/* Hardware parameters */
hardwareParameters_t gHardwareParameters;


This data occupies quite some RAM and ROM.
