Note:The function to monitor the basic clock directly at external is not provided for hardware, however, with dis-
abling 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 adjust-
ment in advance.
