Notes: 1. All-erasure is performed. After that, the specified block can be erased.
2. First, the reset vector is fetched from the embedded program storage area. After the
flash memory related registers are checked, the reset vector is fetched from the user
boot MAT.
3. 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 17.8.2, User Program Mode.
