1. tCH + tCL must be greater than or equal to 1/ fC.
2. Value guaranteed by characterization, not 100% tested in production.
3. When using PP and PW instructions to update consecutive bytes, optimized timings are obtained with one sequence
including all the bytes versus several sequences of only a few bytes (1 ≤ n ≤ 256).
