* The figures given for maximum counting speed are for incrementing or decrementing operation with a prescale value
of ×1. If prescaling is used and 5 kHz is set, the maximum counting speed will be reduced to about half. The maximum
counting speed will also be reduced to about half when the up/down mode is selected.
