detected, the count value of the 16-bit counter is stored in the TPnCCRm register, and a capture interrupt request
signal (INTTPnCCm) is generated.
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.

When the TPnCE bit is set to 1, the 16-bit counter starts counting. When the valid edge input to the TIOPnm pin is
The 16-bit counter continues counting in synchronization with the count clock. When it counts up to FFFFH, it
