High speed clock hse
WebSep 15, 2024 · Low-speed and high-speed crystal are two seperate things. The high-speed clock, which can be either the HSI (high-speed-internal, RC oscillator, 8MHz) or the HSE (high-speed-external, quartz, usually 8MHz). It is used either directly or through a PLL (phase-locked-loop) to derive the core speed. WebBy default, the HSI, or high-speed internal, clock is the clock used as the system clock. However, we can change this to either the HSE clock or the PLL clock. In comparison to the HSI clock, the HSE clock offers an advantage in that it is more accurate than the HSI clock, which relies on RC circuitry to generate the clock signal.

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 …
