(1) HSI is a high-speed internal clock, RC oscillator, with a frequency of 8MHz and low accuracy. (2) HSE is a high-speed external clock, which can be connected with quartz/ceramic resonator or external clock source. Its frequency range is from 4MHz to 16MHz.

[SOLVED]Proper clock initialization for STM32F401RB

WebNov 2, 2024 · Re: STM32 clock gets modified when debugger is connected. I dumped the RCC_CFGR value through UART when running standalone without the debugger and got the value as 0x0011000A. This corresponds to HSE clock (8 MHz) with no division and PLL scale of 6, resulting in the correct 48MHz 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)).
