Function esp_idf_bindgen::rtc_clk_32k_bootstrap

pub unsafe extern "C" fn rtc_clk_32k_bootstrap(cycle: u32)

@brief Enable 32k oscillator, configuring it for fast startup time. Note: to achieve higher frequency stability, rtc_clk_32k_enable function must be called one the 32k XTAL oscillator has started up. This function will initially disable the 32k XTAL oscillator, so it should not be called when the system is using 32k XTAL as RTC_SLOW_CLK.

@param cycle Number of 32kHz cycles to bootstrap external crystal. If 0, no square wave will be used to bootstrap crystal oscillation.
