When the TPnCE bit is set to 1, the 16-bit counter starts counting. When the
valid edge input to the TIPnm pin is detected, the count value of the 16-bit
counter is stored in the TPnCCRm register, and a capture interrupt request
signal (INTTPnCCm) is generated.
The 16-bit counter continues counting in synchronization with the count clock.
When it counts up to FFFFH, it generates an overflow interrupt request signal
(INTTPnOV) at the next clock, is cleared to 0000H, and continues counting. At
this time, the overflow flag (TPnOPT0.TPnOVF bit) is also set to 1. Clear the
overflow flag to 0 by executing the CLR instruction by software.
