            CPU clock frequency used (default 96 MHz).
            Please note that peripherals such as I2C or SPI might not work at
            the specified clock frequency if the selected CPU clock frequency
            is too low. These peripherals are clocked by the APB clock, which
            has a clock rate of 32 MHz for CPU clock frequencies greater than
            or equal to 32 MHz, but is equal to the CPU clock frequency for
            CPU clock frequencies less than 32 MHz. Thus, for SPI, the APB
            clock rate must be at least five times the SPI clock rate. For the
            I2C hardware implementation, the APB clock rate must be at least
            3 MHZ to use I2C in fast mode with a I2C clock rate of 400 kHz.
            For the I2C software implementation, the maximum I2C clock rate
            is 1/130 times the CPU clock rate.
