Notes:

1. “X” denotes the operation available.

2. Configurative Partition Dual Work Restrictions:

Status register reflects partition state, not WSM (Write State Machine) state - this allows a status register for each partition.

Only one partition can be erased or programmed at a time - no command queuing.

Commands must be written to an address within the block targeted by that command.
