    Program/Erase Operations
    These devices are capable of several modes of programming and or erase operations which are described in
    detail in the following sections.
    During a write operation, the system must drive CE# and WE# to V
    IL
    and OE# to VIH when providing an
    address, command, and data. Addresses are latched on the last falling edge of WE# or CE#, while data is
    latched on the 1st rising edge of WE# or CE#.
    The Unlock Bypass feature allows the host system to send program commands to the Flash device without
    first writing unlock cycles within the command sequence. See
    Section 7.7.8
    for details on the Unlock Bypass
    function.
    Note the following:
    When the Embedded Program algorithm is complete, the device returns to the read mode.
    The system can determine the status of the program operation by using DQ7 or DQ6. Refer to the Write
    Operation Stat section for information on these status bits.
    An “0” cannot be programmed back to a “1.” A succeeding read shows that the data is still “0.”
    Only erase operations can convert a “0” to a “1.”
    Any commands written to the device during the Embedded Program Algorithm are ignored except the
    Program Suspend command.
    Secured Silicon Sector, Autoselect, and CFI functions are unavailable when a program operation is in
    progress.
    A hardware reset immediately terminates the program operation and the program command sequence
    should be reinitiated once the device has returned to the read mode, to ensure data integrity.
    Programming is allowed in any sequence and across sector boundaries for single word programming
    operation.
    Programming to the same word address multiple times without intervening erases is permitted.
    7.7.1
    Single Word Programming
    Single word programming mode is one method of programming the Flash. In this mode, four Flash command
    write cycles are used to program an individual Flash address. The data for this programming operation could
    be 8 or 16-bits wide.
    While the single word programming method is supported by all Spansion devices, in general it is not
    recommended for devices that support Write Buffer Programming. See
    Table 12.1 on page 61
    for the
    required bus cycles and
    Figure 7.1
    for the flowchart.
    When the Embedded Program algorithm is complete, the device then returns to the read mode and
    addresses are no longer latched. The system can determine the status of the program operation by using
    DQ7 or DQ6. Refer to the Write Operation Status section for information on these status bits.
    During programming, any command (except the Suspend Program command) is ignored.
    The Secured Silicon Sector, Autoselect, and CFI functions are unavailable when a program operation is in
    progress.
    A hardware reset immediately terminates the program operation. The program command sequence should
    be reinitiated once the device has returned to the read mode, to ensure data integrity.
    Programming to the same address multiple times continuously (for example, “walking” a bit within a word)
    is permitted.
