Notes: 1. Prewriting (setting erase block data to all 0) is not necessary.
2. The values of x, y, z, α, β, γ, ε, η, θ, and N are shown in section 26.1.6, Flash Memory Characteristics.
3. Verify data is read in 16-bit (W) units.
4. Set only one bit in EBR1 or EBR2. More than one bit cannot be set.
5. Erasing is performed in block units. To erase a number of blocks, the individual blocks must be erased sequentially.
