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.

Protection Description
1
1
Both security bits unprogrammed. No program security features enabled. EPROM is programmable and verifiable.
1
0
Only security bit 1 programmed. Further EPROM programming is disabled. Security bit 2 may still be programmed.
0
1
Only security bit 2 programmed. This combination is not supported.
0
0
Both security bits programmed. All EPROM verification and programming are disabled.
