BLOCK WRITE protection is enabled by programming the status register with top ¼, top
½ or entire array of write protection. Separate program enable and program disable
instructions are provided for additional data protection. Hardware data protection is pro-
vided via the WP pin to protect against inadvertent write attempts to the status register.
The HOLD pin may be used to suspend any serial communication without resetting the
serial sequence.

*NOTICE:
Stresses beyond those listed under “Absolute Maxi-
mum Ratings” may cause permanent damage to the
device. This is a stress rating only and functional
operation of the device at these or any other condi-
tions beyond those indicated in the operational sec-
tions of this specification is not implied. Exposure to
absolute maximum rating conditions for extended
periods may affect device reliability.
