Read the lock status (M24M02-DR 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.
