*6 : Reset to the read mode. The Write to Buffer Abort Reset command is required after the Write to Buffer

operation was aborted.

*7 : This command is valid while RESET = VID.

*8 : Sector Group Address (SGA) with A6 = 0, A3 = 0, A2 = 0, A1 = 1, and A0 = 0

*9 : The valid address are A6 to A0.

*10 : The HiddenROM Entry command is required prior to the HiddenROM programming.

*11 : This command is valid during HiddenROM mode.

*12 : The data “F0h” is also acceptable.

*13 : Indicates read cycle.

Notes :

• X = “H” or “L”

• Bus operations are defined in “User Bus Operations Table”.

*1 : At Word mode, a read cycle at address 01h outputs device code. When 227Eh is output, it indicates that reading

two additional codes, called Extended Device Codes, will be required. Therefore the system may continue

reading out these Extended Device Codes at the address of 0Eh, as well as at 0Fh.

*2 : Outputs 01h at protected sector group addresses and outputs 00h at unprotected sector group addresses.

*3 : Given CE = Fix, wait for one cycle after the rising edge of WE (the last write command), then indicate SGA as

(A6, A3, A2, A1, A0) = (0, 0, 0, 1, 0).
