X96012
Data Protection
There are four levels of data protection designed into the
X96012:
1- Any Write to the device first requires setting of the WEL bit
in Control 6 register;
2- The Block Lock can prevent Writes to certain regions of
memory;
3- The Write Protection pin disables any writing to the
X96012;
4- The proper clock count, data bit sequence, and STOP
condition is required in order to start a nonvolatile write cycle,
otherwise the X96012 ignores the Write operation.
WP: Write Protection Pin
When the Write Protection (WP) pin is active (LOW), any
Write operations to the X96012 is disabled, except the
writing of the WEL bit.
