Notes:<br />
1. The output state shows the type of data that appears at the outputs if the partition address is the same as the command<br />
address.<br />
— A partition can be placed in Read Array, Read Status or Read ID/CFI, depending on the command issued.<br />
— Each partition stays in its last output state (Array, ID/CFI or Status) until a new command changes it. The next WSM<br />
state does not depend on the output state of the partition.<br />
— For example, if the partition #1 output state is Read Array and the partition #4 output state is Read Status, every read<br />
from partition #4 (without issuing a new command) outputs the Status register.<br />
2. Illegal commands are any commands not defined in the command set.<br />
