9.2.9 I/O State in Flash*Freeze Mode
(Ask a Question)By default, all I/Os become tri-stated when the device goes into
         Flash*Freeze mode. You can override this default behavior by setting one of the following
         two values:
      - LAST_VALUE—When set to this value, it preserves the previous state of the I/O. This means the I/O remains in the same state in which it had functioned before the device went into Flash*Freeze mode.
 - LAST VALUE_WP—When set to this value, it preserves the last value with weak pull-up.
 
Note: This I/O attribute is applicable for
         SmartFusion 2 and IGLOO 2 families only.
