Block write protection is enabled by programming the status register with one of four blocks of write protection.
Separate 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 “Abso-
lute Maximum Ratings” may cause perma-
nent damage 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 con-
ditions for extended periods may affect
device reliability.
