115 /* Start LSI calibration */ in measure_lsi_frequency()
134 * Calculate LSI frequency from calibration results and update in measure_lsi_frequency()
137 * LSI calibration counts the amount of 16MHz clock half-periods that in measure_lsi_frequency()
141 * elapsed while waiting for @p STM32_WB0_LSI_MEASURE_WINDOW_SIZE LSI periods in measure_lsi_frequency()

150 * ==> LSI period: in measure_lsi_frequency()
158 * ==> LSI frequency: in measure_lsi_frequency()
