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.
