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):
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
