5.5 Block Locking State Transitions upon F-WP Transition
Notes:
2. State transition from the current state [011] to the next state depends on the previous state.
3. When F-WP is driven to V
Other than [110]
1. “F-WP = 0 1” means that F-WP is driven to V
4. In this state transitions table, assumes that lock configuration commands are not written in previous, current and next state.
