| here is the AP-MRD partition to save the predefined common parameters (the device model has same paramters). |
| It's can able to be upgraded over the air. The paramater files including MEP,audio calibration files,etc. |

| CP MRD ==> MRD-C (Const,single UE specific RO data, e.g.RF cal data, MAC address) |
| AP MRD ==> MRD-A (All device same, NV data for the UE model, e.g. audio cal data, fixed part of MEP data) |
| MEP ==> MRD-B (Background R/W, protected single UE specific RW data,e.g changable part of MEP data) |
