3. All partitions default to Read Array mode at power-up. A Read Array command issued to a busy partition results in<br />
undetermined data when a partition address is read.<br />
4. Both cycles of two-cycle commands must be issued to the same partition address. If the two cycles are issued to different<br />
partitions, the address used for the second write cycle determines the active partition. Both partitions output status<br />
information when read.<br />
5. If the WSM is active, both cycles of a two-cycle command are ignored. This feature differs from previous Numonyx flash<br />
memory devices.<br />
6. The Clear Status command clears status register error bits, except when the WSM is running (Pgm Busy, Erase Busy, Pgm<br />
Busy In Erase Suspend, OTP Busy, EFP modes) or suspended (Erase Suspend, Pgm Suspend, Pgm Suspend In Erase<br />
Suspend).<br />
7. EFP writes are allowed only when status register bit SR.0 = 0. EFP is busy if the Block Address = the address at the EFP<br />
Confirm command. Any other commands are treated as data.<br />
8. The current state is the state of the WSM, not the state of the partition.<br />
9. Confirm commands (Lock Block, Unlock Block, Lock-down Block, Configuration Register) perform the operation and then<br />
move to the Ready State.<br />
10. In Erase suspend mode, the only valid two-cycle commands are Program Word, Lock/Unlock/Lockdown Block, and CR<br />
Write. Both cycles of other two-cycle commands (Program OTP & confirm, EFP Setup & confirm, Erase setup & confirm) are<br />
ignored. In Program suspend or Program suspend in Erase suspend, both cycles of all two-cycle commands are ignored.<br />
