NOTES:
1. "WP#=0→1" means that WP# is driven to VIH and "WP#=1→0" means that WP# is driven to
VIL.
2. State transition from the current state [011] to the next state depends on the previous state.
3. When WP# is driven to VIL 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.
