commands are issued and consume more than a certain level of free space in the flash memory. This operation
occurs at every module initialization (power-on).
If supply voltage becomes non-defined states during initialization or writing in flash memory, data in
flashmemory might be destroyed. If the data in flash memory is destroyed, module will not work correctly.
Therefore please be sure to stabilize power source before RESET release.
In addition please design module peripheral circuits to avoid temporary blackout of power source during
operation.Please refer HD-AE-C 051089 for HCI command which rewrites flash memory data.
