Notes: 1. All-erasure is performed. After that, the specified block can be erased.
2. In this LSI, the user programming mode is defined as the period from the timing when a
program concerning programming and erasure is started to the timing when the
program is completed. For details on a program concerning programming and erasure,
see section 24.8.2, User Program Mode.
