Command
X Don’t Care, PA Program Address, PD Program Data, BA Any address in the Block, BKA Bank Address, WBL Write Buffer Location. All
values in the table are in hexadecimal.
The maximum number of cycles in the command sequence is 37. N+1 is the number of Words to be programmed during the Write to Buffer
and Program operation.
Each buffer has the same A5-A22 addresses. A0-A4 are used to select a Word within the N+1 Word page.
The 6th cycle has to be issued N time. WBL scans the Word inside the page.
BA must be identical to the address loaded during the Write to buffer and Program 3rd and 4th cycles.
The Unlock Bypass Program command can be used to program one address in the memory
array at a time. The command requires two Bus Write operations, the final write operation
latches the address and data and starts the Program/Erase Controller.
The Program operation using the Unlock Bypass Program command behaves identically to the
Program operation using the Program command. The operation cannot be aborted, a Bus
Read operation to the Bank where the command was issued outputs the Status Register. See
the Program command for details on the behavior.
The Unlock Bypass Reset command can be used to return to Read/Reset mode from Unlock
Bypass mode. Two Bus Write operations are required to issue the Unlock Bypass Reset
command. Read/Reset command does not exit from Unlock Bypass mode.
