NOTES:
1.
2.
Bus operations are defined in Table 3.
Following the Read Configuration or Read Query commands, read operations output device configuration or CFI query
information, respectively. See Section 3.2.2 and 3.2.4.
Either 40H or 10H command is valid, but the Intel standard is 40H.
When writing commands, the upper data bus [DQ
8
–DQ
15
] should be either V
IL
or V
IH
, to minimize current draw.
First cycle command addresses should be the same as the operation’s target address. Examples: the first-cycle address
for the Read Device Identification Codes command should be the same as the Identification Code address (IA); the first
cycle address for the 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.
IA
= Identification code address.
BA
= Address within the block..
PA
= User programmable 4-word protection address in the device identification plane.
QA
= Query code address.
WA
= Word address of memory location to be written.
SRD = Data read from the status register.
WD
= Data to be written at location WA is latched on the rising edge of WE# or CE# (whichever goes high first).
ID
= Identification code data.
PD
= User programmable 4-word protection data.
QD
= Query code data.
