These timings are given for a 40 kHz clock but the microcontroller’s internal RC frequency can vary from 30 to 60 kHz. Moreover, given an exact RC oscillator frequency, the exact timings still depend on the phasing of the APB interface clock versus the LSI clock so that there is always a full RC period of uncertainty. 2. Data based on characterization results, not tested in production. Table 70.
