Note:
1. Tested with clock frequency lower than 50 MHz.
2. tW can be up to 45 ms at -40℃ during the characterization of the current design. It will be improved in the future design.
3. For multiple bytes after first byte within a page, tBPn = tBP1 + tBP2 * N, where N is the number of bytes programmed.
