*1: The current flowing through internal pull-up resistor, power-ON reset circuit (mask option), and
comparator circuit is not included
2: The oscillation stabilization wait time is the time during which the CPU is stopped to prevent
unstable operation when oscillation is started.
3: Depends on the setting of the basic interval timer mode register (BTM) as follows:
