        There are 2 modes:
        • External crystal - The following items are displayed in this mode:
          • Clock frequency [MHz] - Frequency of the crystal or the external clock. The crystal should be in the range of 32-38.4kHz or 1-16MHz and the external clock should be in the range of 0.0001-40MHz but this limits may be further restricted by other settings of the ICS module (Oscillator operating mode, FLL/PLL mode).
