5.5 Block Locking State Transitions upon F-WP Transition
(4)
Notes:
1. “F-WP = 0
1” means that F-WP is driven to V
IH
and “F-WP = 1
0” means that F-WP is driven to V
IL
.
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
IL
in [110] state, the state changes to [011] and the blocks are automatically locked.
4. In this state transitions table, assumes that lock configuration commands are not written in previous, current and next state.
