It is specified when SC pin is selected to the 3-state output by the mask option.
It is specified when SC pin is selected to the pull-up resistance by the mask option. As the
restriction by this item, take notice that it limits the upper limit of the system clock frequency fc.
It is specified when SOA and PX1/SOB pins are selected to the 3-state output by the mask option.
It is specified when SOA and PX1/SOB pins are selected to the pull-up resistance by the mask option.
