• Capture operation
When the TPkCE bit is set to 1, the 16-bit counter starts counting. When the valid edge input to the TIPka pin is
detected, the count value of the 16-bit counter is stored in the TPkCCRa register, and a capture interrupt request
signal (INTTPkCCa) 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 (INTTPkOV) at the next clock, is cleared to 0000H, and continues
counting. At this time, the overflow flag (TPkOPT0.TPkOVF bit) is also set to 1. Confirm that the overflow flag is
set to 1 and then clear it to 0 by executing the CLR instruction via software.
