BLOCK WRITE protection is enabled by programming the status register with one of four blocks of write protection. Sepa-
rate program enable and program disable instructions are provided for additional data protection. Hardware data protection
is provided 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
Maximum Ratings” may cause permanent dam-
age to the device. This is a stress rating only and
functional operation of the device at these or any
other conditions beyond those indicated in the
operational sections of this specification is not
implied. Exposure to absolute maximum rating
conditions for extended periods may affect device
reliability.
