1. tCH + tCL must never be lower than the shortest possible clock period, 1/fC(max).
2. Value guaranteed by characterization, not 100% tested in production.
3. tCLQV must be compatible with tCL (clock low time): if tSU is the Read setup time of the SPI bus master, tCL must be equal to
(or greater than) tCLQV+tSU.
