Question about the above PWR_LPSLEEP example code.
My test setup includes this:
* STM32CubeIDE Version: 1.17.0, Build: 23558_20241125_2245 (UTC).
* HAL library STM32Cube_FW_G0_V1.6.2.
* NUCLEO-G0B1RE.
The example code in main() reduces the clock frequency (lines 123-124):
/* Reduce the System clock to below 2 MHz */
SystemClock_Decrease();
What is the advantage of the reduced clock frequency, as the Cortex-M0+ CPU clock is already off in LP Sleep Mode? The Reference Manual RM0444 states on page 128that this has "no effect on other clocks or analog clock sources". Does the reduced system clock frequency save power by reducing the clock for all other clocks or analog clock sources?
Thank you for your response.
