38 / 226 page  Supply, reset and clock management ST7FOXF1, ST7FOXK1, ST7FOXK2 38/226 Figure 12. Clock management block diagram 6.2 Multi-oscillator (MO) The main clock of the ST7 can be generated by four different source types coming from the multi-oscillator block (1 to 16 MHz): ● An external source ● 5 different configurations for crystal or ceramic resonator oscillators ● An internal high frequency RC oscillator Each oscillator is optimized for a given frequency range in terms of consumption and is selectable through the option byte. The associated hardware configurations are shown in Table 8. Refer to the electrical characteristics section for more details.
