MX29F800T/B
COMMAND DEFINITIONS
Device operations are selected by writing specific ad-
dress and data sequences into the command register.
Writing incorrect address and data values or writing them
in the improper sequence will reset the device to the
read mode. Table 1 defines the valid register command
sequences. Note that the Erase Suspend (B0H) and
Erase Resume (30H) commands are valid only while
the Sector Erase operation is in progress. Either of the
two reset command sequences will reset the
device(when applicable).
