available to the user, even if the device is secured. These

bits can be used for user-specific data.

Input and I/O Pull-ups

All ATF22V10B family members have internal input and I/O

pull-up resistors. Therefore, whenever inputs or I/Os are

ensures that all logic array inputs are at known states.

These are relatively weak active pull-ups that can easily be

overdriven by TTL-compatible drivers (see input and I/O

diagrams below).
