10. Preload of Registered Outputs
The Atmel® ATF22V10B registers are provided with circuitry to allow loading of each register with either a high or a
low. This feature will simplify testing since any state can be forced into the registers to control test sequencing. A
JEDEC file with preload is generated when a source file with vectors is compiled. Once downloaded, the JEDEC
file preload sequence will be done automatically by most of the approved programmers after the programming.

11. Security Fuse Usage
A single fuse is provided to prevent unauthorized copying of the ATF22V10B 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.
12. 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.
13. Programming/Erasing
Programming/erasing is performed using standard PLD programmers. See CMOS PLD Programming
Hardware and Software Support for information on software/programming.
