, the clock is released only when this bit is set to '1' by hardware. HSE crystals can be enabled and disabled by setting the hseon bit in rcc_cr in the clock control register.The clock source is formed by the combination of an external passive crystal and the MCU internal clock driving circuit. It has a certain start time and a high accuracy. To reduce clock output distortion and reduce startup stability, the crystal/Ceramic Resonator and load capacitance must be as close as possible to the osc
