1. Technology T7Y devices are identified by process identification digit "X" in the device marking.
2. When using the Page Program (PP) instruction to program consecutive bytes, optimized timings are
obtained with one sequence including all the bytes versus several sequences of only a few bytes. (1 ≤ n ≤
