54.14 Nonvolatile Item Read/Write
The Nonvolatile Item functions allow you to inspect and modify settings for Qualcomm chipset based devices by reading and writing items over the Qualcomm NV interface.
The dialog is limited to 4 bytes; this is however sufficient to cover most basic NV items.
Specifics on the NV interface are vendor proprietary and must be obtained from the vendor.

WARNING:It is possible to corrupt the device's calibration parameters or otherwise damage the device by writing the wrong value to the wrong address. You are always prompted to confirm an NV command before it is executed. |
Before an NV write, a read is always performed at the same address. All traffic over the NV interface is logged in internal protocol reports, so if you are recording a logfile in TEMS Investigation it should be possible to recover the previous values of parameters by studying these reports.
After an NV write the device is always automatically reset, and consequently it is deactivated in TEMS Investigation.
