Table 4 : Commands
Note : X : Don’t Care, PA : Program Address, PD : Program Data, BA : Any address in the Block.
All values in the table are in hexadecimal.
The Command Interface only uses address bits A0-A10 to verify the commands, the upper
address bits are Don’t Care.
Read/Reset.
After a Read/Reset command, read the memory as normal until another command is issued.
Auto Select.
After an Auto Select command, read Manufacturer ID, Device ID or Block Protection Status.
Program, Unlock Bypass Program, Chip Erase, Block Erase.
After these commands read the Status Register until the Program/Erase Controller completes and
the memory returns to Read Mode. Add additional Blocks during Block Erase Command with
additional Bus Write Operations until the Timeout Bit is set.
Unlock Bypass.
After the Unlock Bypass command issue Unlock Bypass Program or Unlock Bypass Reset
commands.
Unlock Bypass Reset.
After the Unlock Bypass Reset command read the memory as normal until another command is
issued.
Erase Suspend.
After the Erase Suspend command read non-erasing memory blocks as normal, issue Auto Select
and Program commands on non-erasing blocks as normal.
Erase Resume.
After the Erase Resume command the suspended Erase operation resumes, read the Status Register
