Summary

This PR fixes/implements the following bugs/features

  • ADC/DAC input clock is too high
  • LPUART clock is low
  • Optimize PLL ratio
  • There were no plans to change LPUART, but since it will be lower than current value when I fix ADC/DAC problem, I changed it as described in Incorrect clock settings for NUCLEO-H563ZI #2505.
  • By setting SRC / M = 2 N = 250 for PLL1/2/3 you can flexibly determine clock source frequency and easily calculate division P/Q/R.

e.g. Generic boards and NUCLEO-H563ZI are portable by simply changing value of PLLM.
