1. tCH + tCL must be greater than or equal to 1/ fC(max)
2. Value guaranteed by characterization, not 100% tested in production.
3. Expressed as a slew-rate.
4. Only applicable as a constraint for a WRSR instruction when SRWD is set at 1.
5. 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 ≤256).
6. VPPH should be kept at a valid level until the program or erase operation has completed and its result (success or failure) is
known.
