Instructions

5.4

Read the lock status (M24512-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.
