Note In the external event count mode, when the TQ0CTL0.TQ0CE bit is set to 1 (operation starts),
Remark
the 16-bit counter is cleared from FFFFH to 0000H at the same time. The first count operation
starts from 0001H every time the valid edge of the external event count input is detected.
Therefore, the count of the first count operation is one number smaller than the count of second
or subsequent count operation.
This figure shows the basic timing when the rising edge is specified as the valid edge of the
external event count input.
