through
Figure 38
show 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, CFI Query or Read Status
Register) until a new command changes it. The next WSM state does not depend on the partition’s
output state.
