WebSW[1:0] is used to set the system clock. Since I am using the PLL_P as the system clock, I will write a 2 (1:0) to the SW Bits; SWS[3:2] is used to monitor the status of the system clock. So here we will wait for these bits to indicate that the PLL_P has been set as the system clock (wait for the SWS bits to indicate 2 (1:0)). WebFor the RCC code generated using HAL, although the code runs in the debug mode, the system clock and timer clock frequencies are not the same as it mean to be (96MHz/48MHz). This was tested by setting timer pre-scaler and Auto reload register and check the update event.
