Product Identification Mode Exit/Reset
In order to return to the standard Read mode, the Software
Product Identification mode must be exited. Exit is accom-
plished by issuing the Software ID Exit command
sequence, which returns the device to the Read operation.
Please note that the Software ID Exit command is ignored
during an internal Program or Erase operation. See Table 4
for software command codes, Figure 12 for timing wave-
form, and Figure 18 for a flowchart.
