M24M02 I2C EEPROM Read Lock Status

I am looking at the data sheet for the M24M02 and I want to read the Lock Status.  The data sheet says this


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.


If I send the ID Page Write instruction plus one data byte, won't that actually write the data byte if the ID page is not locked?

Or does this mean to send the Device ID byte plus one byte (which would be the first address byte in a real write command)?


Thanks for your help.
