Commands other than those shown above are reserved by Intel for future device implementations and should not be used.
Bus operations are defined in Table 2.
X = Any valid address within the device.
IA = Identifier Code Address.
BA = Address within the block being erased.
WA = Address of memory location to be written.
RCD = Data to be written to the read configuration register. This data is presented to the device on A
15-0
; set all other
address inputs to
“0.”
SRD = Data read from status register. See Table 5 for a description of the status register bits.
WD = Data to be written at location WA. Data is latched on the rising edge of WE# or CE# (whichever goes high first).
ID = Data read from identifier codes. See Table 4 for manufacturer and device codes.
RCD = Data to be written to read configuration register. See Table 6 for a description of the read configuration register bits.
Following the Read Identifier Codes command, read operations access manufacturer, device codes, and read
configuration register.
Following a block erase, program, and suspend operation, read operations access the status register.
To issue a block erase, program, or suspend operation to a lockable block, hold WP# at V
IH
.
Either 40H or 10H are recognized by the WSM as the program setup.
