Data Sheet
2.1.4
The microcontroller clock is provided by the pin MCLK. Three clock rates are selectable
by a programmable prescaler (see chapter clock generation figure 89) which is
controlled by the MODE1.MCLK bit corresponding to the following table.
The possible MCLK frequencies are listed in table 6.
