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

read mode. Table 4 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.
