later.
Notes:
1.
2. All values are in hexadecimal.
3. Except for the read cycle and the fourth cycle of the autoselect
4. Data bits DQ15–DQ8 are don’t care in command sequences,
5. Unless otherwise noted, address bits A19–A11 are don’t cares.
6. No unlock or command cycles required when bank is in read
7. The Reset command is required to return to reading array data
8. The fourth cycle of the autoselect command sequence is a read
9. The data is 80h for factory locked and 00h for not factory locked.
10. The data is 00h for an unprotected sector/sector block and 01h

PD = Data to be programmed at location PA. Data latches on the rising
edge of WE# or CE#f pulse, whichever happens first.
SADD = Address of the sector to be verified (in autoselect mode) or
erased. Address bits A19–A12 uniquely select any sector.
BA = Address of the bank that is being switched to autoselect mode, is
in bypass mode, or is being erased.
14. The Erase Resume command is valid only during the Erase
15. Command is valid when device is ready to read array data or when
