AA = Array Address
BA = Block Address
IA = Identifier Address
WA = Write Address
X = Don’t Care
DATA
AD = Array Data
CSRD = CSR Data
ID = Identifier Data
WD = Write Data
NOTES:
1. Following the intelligent identifier command, two Read operations access the manufacturer and device signature codes.
2. The CSR is automatically available after device enters Data Write, Erase or Suspend operations.
3. Clears CSR.3, CSR.4, and CSR.5. Also clears GSR.5 and all BSR.5 and BSR.2 bits. See Status register definitions.
4. While device performs Block Erase, if you issue Erase Suspend command (B0H), be sure to confirm ESS (Erase-Suspend-Status) is
set to 1 on compatible status register. In the case, ESS bit was not set to 1, also completed the Erase (ESS = 0, WASM = 1), be sure
to issue Resume command (D0H) after completed next Erase command. Beside, when the Erase Suspend command is issued,while
the device is not in Erase, be sure to issue Resume command (D0H) after the next erase completed. When you use Erase Suspend/
Resume command, we recommend to issue serial Block Erase command (20H, D0H) and Resume command (D0H). (Refer to Perfor-
mance Enhancement Command Bus Definitions.)
