Notes: 1. Prewriting (writing 0 to all data in erased block) is not necessary.
2. The values of x, y, z, , ,
3. Verify data is read in 16-bit (word) units.
4. Set only a single bit in EBR1 and EBR2. Do not set more than one bit.
5. Erasing is performed in block units. To erase multiple blocks, each block must be erased in turn.
