and types of flash memory.
If supply voltage becomes non-defined states during initialization or writing in flash memory, data in flash
memory 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 051267 for HCI command which rewrites flash memory data.

controlled by Firmware. When the free space in flash memory is lower than certain amount, Defrag
automatically starts. Amount of time required for Defrag will vary depending on the environment. Please
conduct enough verification for the time required for the customer’s product under customer’s environment
before use.
sure to control by open drain.
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).
