7.4.2 Subsystem clock oscillator
XT2 pins.
and an inverted-phase clock signal to the XT2 pin.
134
The subsystem clock oscillator oscillates with a crystal resonator (32.768 kHz TYP.) connected to the XT1 and
External clocks can be input to the subsystem clock oscillator. In this case, input a clock signal to the XT1 pin
Figure 7-5 shows an external circuit of the subsystem clock oscillator.
