Which one below is the appropriate formula for Calculating the I2C Clock Speed
technology embedded technologies

  1. PeripheralClock = ((I2C(ClockFreq)) / (I2CLowCycle+I2CHighCycle))

  2. I2C(ClockFreq) = ((PeripheralClock) / (I2CLowCycle+I2CHighCycle))

  3. I2C(ClockFreq) = ((I2CLowCycle+I2CHighCycle) / (PeripheralClock))

  4. PeripheralClock = ((I2C(ClockFreq)) / (I2CLowCycle * I2CHighCycle))
