Write State Machine
The Next State Table shows the command state transitions (Next State Table) based on
incoming commands. Only one partition can be actively programming or erasing at a
time. Each partition stays in its last read state (Read Array, Read Device ID, Read CFI
or Read Status Register) until a new command changes it. The next WSM state does
not depend on the partition’s output state.
