WebThe HSI clock is enabled by default, so it would not need any configuration. After this, we must wait until the HSE clock from the external crystal oscillator stabilizes. The oscillator must produce stable output before it can be used. This is one advantage of the HSI signal in that it has less startup time. WebThe original HSICAL can always be reset by restoring the default on-reset value of HSITRIM, which, unfortunately, differs depending on chip rev.
