The system clock controller consists of a clock generator, a timing generator, and a standby

to the CPU core and peripheral hardware. It contains two oscillation circuits: one for the
high-frequency clock and one for the low-frequency clock. Power consumption can be
reduced by switching of the standby controller to low-power operation based on the
low-frequency clock.
a resonator between the XIN/XOUT and XTIN/XTOUT pins respectively. Clock input from
an external oscillator is also possible. In this case, external clock is applied to XIN/XTIN
pin with XOUT/XTOUT pin not connected.
Note: The function to monitor the basic clock directly at external is not provided for hardware,
XOUT
The clock generator generates the basic clock which provides the system clocks supplied
The high-frequency (fc) and low-frequency (fs) clocks can easily be obtained by connecting

however, with disabling all interrupts and watchdog timers, the oscillation frequency can
be adjusted by monitoring the pulse which the fixed frequency is outputted to the port by
the program.
The system to require the adjustment of the oscillation frequency should create the
program for the adjustment in advance.
