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