P30-65nm SBC
A.3
Write State Machine
Show here are 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.
Note:
IS refers to Illegal State in the Next State Tables.
