*1. The clock cycle of the SCK clock (frequency f_SCK) is 1/f_SCK µs. This clock cycle is determined by a combination of
several AC characteristics. Note that the clock cycle cannot be set as (1/f_SCK) = t_LOW (Min.) + t_HIGH (Min.) by minimizing
the SCK clock cycle time.
*2. These are values of sample and not 100% tested.
