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. |
