: Instruction cycle
: Not affected by the gear.
: The gear affects the operating speed or other settings.
: The time-base timer stops when the oscillation frequency clock halts.
: Output of the time-base timer is selectable when the A/D converter is activated continuously.
Other operations are affected by the gear.
