Function esp_idf_bindgen::rtc_clk_apb_freq_update

pub unsafe extern "C" fn rtc_clk_apb_freq_update(apb_freq: u32)

@brief Store new APB frequency value into RTC_APB_FREQ_REG

This function doesn't change any hardware clocks.

Functions which perform frequency switching and change APB frequency call this function to update the value of APB frequency stored in RTC_APB_FREQ_REG (one of RTC general purpose retention registers). This should not normally be called from application code.

@param apb_freq new APB frequency, in Hz
