Notes:
1.
The output state shows the type of data that appears at the outputs if the partition address is the same as the command
address.
— A partition can be placed in Read Array, Read Status or Read ID/CFI, depending on the command issued.
— 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 output state of the partition.
— For example, if the partition #1 output state is Read Array and the partition #4 output state is Read Status, every read
from partition #4 (without issuing a new command) outputs the Status register.
