9.1.5
Standby
De-asserting CE# deselects the device and places it in standby mode, substantially reducing device
power consumption. In standby mode, outputs are placed in a high-impedance state independent of
OE#. If deselected during a program or erase algorithm, the device shall consume active power
until the program or erase operation completes.
9.1.6
Reset
The device enters a reset mode when RST# is asserted. In reset mode, internal circuitry is turned
off and outputs are placed in a high-impedance state.
After returning from reset, a time tPHQV is required until outputs are valid, and a delay (tPHWV) is
required before a write sequence can be initiated. After this wake-up interval, normal operation is
restored. The device defaults to read-array mode, the Status Register is set to 80h, and the
Configuration Register defaults to asynchronous page-mode reads.
If RST# is asserted during an erase or program operation, the operation aborts and the memory
contents at the aborted block or address are invalid. See Figure 19, “Reset Operations Waveforms”
on page 48 for detailed information regarding reset timings.
Like any automated device, it is important to assert RST# during system reset. When the system
comes out of reset, the processor expects to read from the flash memory array. Automated flash
memories provide status information when read during program or erase operations. If a CPU reset
occurs with no flash memory reset, proper CPU initialization may not occur because the flash
memory may be providing status information instead of array data. Intel flash memories allow
proper CPU initialization following a system reset through the use of the RST# input. In this
application, RST# is controlled by the same CPU reset signal.
9.2
Device Commands
The device’s on-chip WSM manages erase and program algorithms. This local CPU (WSM)
controls the device’s in-system read, program, and erase operations. Bus cycles to or from the flash
memory conform to standard microprocessor bus cycles. RST#, CE#, OE#, WE#, and ADV#
control signals dictate data flow into and out of the device. WAIT informs the CPU of valid data
during burst reads. Table 18, “Bus Operations Summary” on page 53 summarizes bus operations.
Device operations are selected by writing specific commands into the device’s CUI. Table 19,
“Command Codes and Descriptions” on page 56 lists all possible command codes and
descriptions. Table 20, “Bus Cycle Definitions” on page 58 lists command definitions. Because
commands are partition-specific, it is important to issue write commands within the target address
range.
