Since SCL and SDA are open-collector-type outputs, which the processor can only actively drive low, this

specification applies only when SCL or SDA are driven low by the processor. The time required for SCL or

SDA to reach a high level depends on external signal capacitance and pull-up resistor values.

Since SCL and SDA are open-collector-type outputs, which the processor can only actively drive low, this

specification applies only when SCL or SDA are actively being driven or held low by the processor.

SCL and SDA are internally synchronized.This setup time must be met only if recognition on a particular

clock is required.
