The actual position is affected by the prescale and division values programmed in IFDR.
Inter Peripheral Clock is the clock at which the I
Because SCL and SDA are open-drain-type outputs, which the processor can only actively drive low, the time SCL
or SDA takes to reach a high level depends on external signal capacitance and pull-up resistor values.
