In the following table, data are based on characterization results, not tested in production.
3. The trimming step differs depending on the trimming code. It is usually negative on the codes which are multiples of 16
(0x00, 0x10, 0x20, 0x30...0xE0). Refer to the AN3101 “STM8L15x internal RC oscillator calibration” application note for
more details.
