Read the lock status (M24C64-D)
The locked/unlocked status of the Identification page can be checked by issuing a specific
truncated command [Identification Page Write instruction + one data byte]: this data byte will
be acknowledged if the Identification page is unlocked, while it will not be acknowledged if
the Identification page is locked.
Once the acknowledge bit of this data byte is read, it is recommended to generate a Start
condition followed by a Stop condition, so that:

Acknowledge in Read mode
For all Read commands, the device waits, after each byte read, for an acknowledgment
during the 9
time, the device terminates the data transfer and switches to its Standby mode.
The instruction is truncated and not executed as the Start condition resets the device
internal logic.
The device is set back into Standby mode by the Stop condition.
