5.
Electronic Signature Word
There are 64-bits of programmable memory that are always available to the user, even if the device is secured.
These bits can be used for user-specific data.
6.
Security Fuse Usage
A single fuse is provided to prevent unauthorized copying of the Atmel ATF22LV10CZ/CQZ fuse patterns. Once
programmed, fuse verify and preload are inhibited. However, the 64-bit User Signature remains accessible.
The security fuse should be programmed last, as its effect is immediate.
7.
Programming/Erasing
Programming/erasing is performed using standard PLD programmers. See CMOS PLD Programming
Hardware and Software Support for information on software/ programming.

8.
Input and I/O Pin Keepers
All ATF22LV10CZ/CQZ family members have internal input and I/O pin-keeper circuits. Therefore, whenever
inputs or I/Os are not being driven externally, they will maintain their last driven state. This ensures that all logic
array inputs and device outputs are at known states. These are relatively weak active circuits that can be easily
overridden by TTL-compatible drivers (see input and I/O diagrams below).
