PY32F002B Functional module :
PY32F002B Clock system:
After the CPU starts, the default system clock frequency is HSI 24MHz. After the program runs, the system clock frequency and clock source can be reconfigured. The high-frequency clocks that can be selected are:
24MHz configurable internal high-precision HSI clock.
A 32.768KHz configurable internal LSI clock.
4MHz~32MHz external input clock
32.768KHz LSE clock.
The AHB clock can be divided based on the system clock, while the APB clock can be divided based on the AHB clock. The highest clock frequency for AHB and APB is 24MHz.
