20.6
The bus master clock selection circuit selects the system clock ( ) or one of the medium-speed
clocks ( /2, /4, /8, /16, and /32) to be supplied to the bus master, according to the settings of
the SCK2 to SCK0 bits in SCKCR.

(1) Connecting 32.768kHz Crystal Oscillator
To supply a clock to the subclock oscillator, connect a 32.768kHz crystal oscillator, as shown in
figure 20.8. See section 20.3.1, Connecting a Crystal Resonator.
Figure 20.9 shows the equivalence circuit for a 32.768kHz oscillator.
