Security Bits
When neither of the security bits are programmed, the code in the EPROM can be verified. When only security bit 1 is programmed, all further
programming of the EPROM is disabled. At that point, only security bit 2 may still be programmed. When both security bits are programmed,
EPROM verify is also disabled.

NOTES:
1. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or any conditions other than those described in the AC and DC Electrical Characteristics section
of this specification are not implied.
2. This product includes circuitry specifically designed for the protection of its internal devices from the damaging effects of excessive static
charge. Nonetheless, it is suggested that conventional precautions be taken to avoid applying greater than the rated maximum.
3. Parameters are valid over operating temperature range unless otherwise specified. All voltages are with respect to VSS unless otherwise noted.
