Read the lock status (M24128-D only)
The locked/unlocked status of the Identification page can be checked by transmitting a
specific truncated command [Identification Page Write instruction + one data byte] to the
device. The device returns an acknowledge bit if the Identification page is unlocked,
otherwise a NoAck bit if the Identification page is locked.
Right after this, it is recommended to transmit to the device a Start condition followed by a
Stop condition, so that:
• Start: the truncated command is not executed because the Start condition resets the
device internal logic,
• Stop: the device is then set back into Standby mode by the Stop condition.
