Function esp_idf_sys::pcnt_unit_stop

pub unsafe extern "C" fn pcnt_unit_stop(
    unit: pcnt_unit_handle_t,
) -> esp_err_t

@brief Stop PCNT from counting

@note This function should be called when the unit is in the enable state (i.e. after calling pcnt_unit_enable()) @note The stop operation won’t clear the counter. Also see pcnt_unit_clear_count() for how to clear pulse count value. @note This function is allowed to run within ISR context @note This function will be placed into IRAM if CONFIG_PCNT_CTRL_FUNC_IN_IRAM, so that it is allowed to be executed when Cache is disabled
