Notes:
1.
First-cycle command addresses should be the same as the operation’s target address. Examples: the first-cycle address
for the Read Identifier command should be the same as the Identification code address (IA); the first-cycle address for
the Word Program command should be the same as the word address (WA) to be programmed; the first-cycle address
for the Erase/Program Suspend command should be the same as the address within the block to be suspended; etc.
XX = Any valid address within the device.
IA = Identification code address.
BA = Block Address. Any address within a specific block.
LPA = Lock Protection Address is obtained from the CFI (through the CFI Query command). The Intel Wireless Flash
Memory family’s LPA is at 0080h.
PA = User programmable 4-word protection address.
PnA = Any address within a specific partition.
PBA = Partition Base Address. The very first address of a particular partition.
QA = CFI code address.
WA = Word address of memory location to be written.
2.
SRD = Status register data.
WD = Data to be written at location WA.
IC = Identifier code data.
PD = User programmable 4-word protection data.
QD = Query code data on DQ[7:0].
CD = Configuration register code data presented on device addresses A[15:0]. A[MAX:16] address bits can select any
partition. See Table 28, “Read Configuration Register Descriptions” on page 84 for Configuration Register bits
descriptions.
3.
Commands other than those shown above are reserved by Intel for future device implementations and should not be
used.
