pub enum Clock48MhzSrc {
    Hsi48(Hsi48Config),
    PllQ,
}

Sets the source for the 48MHz clock to the USB and RNG peripherals.

Variants

Hsi48(Hsi48Config)

Use the High Speed Internal Oscillator. For USB usage, the CRS must be used to calibrate the oscillator to comply with the USB specification for oscillator tolerance.

PllQ

Use the PLLQ output. The PLL must be configured to output a 48MHz clock. For USB usage the PLL needs to be using the HSE source to comply with the USB specification for oscillator tolerance.
