I2C CLOCK CHOOSE SYSCLK AND PCLK1

HEY I am having stm32f767zi. As datasheet has mentioned it has 216MHZ CLOCK. NOW PCLK1 is 54Mhz max. So stm32cubemx has 3 option for i2c. SYSCLK , HCLK AND PCLK1. By default stm32cubemx selected pclk1 for i2c which is 54mhz. so can i use sysclk for i...

Resolved! what is the crystal oscillator frequency of UART of STM32f103CB

Hi,​I just read an article mentioned that micro controller will limit (or do smthing) to lower down the frequency of crystal oscillator to match the multiply number of 9600 for UART, is that right?​So if I'm using PLL to boost CPU frequency from 8M t...
