Notes:
1. RA : Read Address , PA : Program Address, RD : Read Data, PD : Program Data , BA : Block Address (A23 ~ A12)
DA : Bank Address (A23 ~ A20) , ABP : Address of the block to be protected or unprotected, CR : Configuration Register Setting
2. The 4th cycle data of autoselect mode and RD are output data. The others are input data.
3. Data bits DQ15–DQ8 are don’t care in command sequences, except for RD, PD and Device ID.
4. Unless otherwise noted, address bits A23–A11 are don’t cares.
5. The reset command is required to return to read mode.
If a bank entered the autoselect mode during the erase suspend mode, writing the reset command returns that bank to the erase suspend mode.
If a bank entered the autoselect mode during the program suspend mode, writing the reset command returns that bank to the program suspend mode.
If DQ5 goes high during the program or erase operation, writing the reset command returns that bank to read mode or erase suspend mode if that
bank was in erase suspend mode.
6. The 3rd and 4th cycle bank address of autoselect mode must be same.
Device ID Data : "22FCH" for Top Boot Block Device, "22FDH" for Bottom Boot Block Device
7. 00H for an unprotected block and 01H for a protected block.
8. 0H for handshaking, 1H for non-handshaking
9. The unlock bypass command sequence is required prior to this command sequence.
10. Quadruple word accelerated program is invoked only at Vpp=VID ,Vpp setup is required prior to this command sequence.
PA1, PA2, PA3, PA4 have the same A23~A2 address.
11. The system may read and program in non-erasing blocks when in the erase suspend mode.
The system may enter the autoselect mode when in the erase suspend mode.
The erase suspend command is valid only during a block erase operation, and requires the bank address.
12. The erase/program resume command is valid only during the erase/program suspend mode, and requires the bank address.
13. This mode is used only to enable Data Read by suspending the Program operation.
14. Set block address(BA) as either A6 = VIH, A1 = VIH and A0 = VIL for unprotected or A6 = VIL, A1 = VIH and A0 = VIL for protected.
15. Command is valid when the device is in Read mode or Autoselect mode.
16. See "Set Burst Mode Congiguration Register" for details.
