Section 18 ROM (H8/3048F-ONE: Single Power Supply, H8/3048B Mask ROM Version)
If erasing multiple blocks, set a single bit in EBR for the next block to be erased, and repeat the
erase/erase-verify sequence as before.

REJ09B0325-0300
Notes: 1. Prewriting (setting erase block data to all 0s) is not necessary.
2. Verify data is read in 16-bit (word) units.
3. Make only a single-bit specification in the erase block register (EBR). Two or more bits must not be set simultaneously.
4. Erasing is performed in block units. To erase multiple blocks, each block must be erased in turn.
5. The wait times and the value of N are shown in section 21.1.6, Flash Memory Characteristics.
