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 partition's output state.
For example, if partition #1's output state is Read Array and partition #4's output state is Read Status, every read from
partition #4 (without issuing a new command) outputs the Status register.
Illegal commands are those not defined in the command set.
