WebThe MCO1 pin can ouput a clock signal either from the HSI (high-speed internal clock), LSE (low-speed external clock), HSE (high-speed external clock), or a PLL (phase locked loop). The MCO2 pin can output a clock signal either from the HSE clock, PLL clock, system clock (SYSCLK), or PLLI2S clock. WebThe HSI clock consists of an RC circuit, which is a resistor-capacitor circuit that oscillates at a specific frequency and can function as the clock. The HSE clock is the external clock …
