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