• Capture operation
When the TPnCE bit is set to 1, the 16-bit counter starts incrementing. When it is detected that a valid edge as
been input to the TIPna pin, the value of the 16-bit counter is stored in the TPnCCRa register, and a capture
interrupt request signal (INTTPnCCa) is generated.
The 16-bit counter continues incrementing in synchronization with the count clock. When the counter reaches
FFFFH, it generates an overflow interrupt request signal (INTTPnOV) at the next clock, is cleared to 0000H, and
continues incrementing. At this time, the overflow flag (the TPnOPT0.TPnOVF bit) is also set to 1. The overflow
flag must be cleared to 0 by executing a CLR1 software instruction.
