valid edge has been input to the TIQ0m pin, the value of the 16-bit counter is stored in the TQ0CCRm register, the 16-
bit counter is cleared to 0000H, and a capture interrupt request signal (INTTQ0CCm) is generated.
overflow interrupt request signal (INTTQ0OV) is generated at the next count clock, and the counter is cleared to
0000H and continues incrementing. At this time, the overflow flag (TQ0OPT0.TQ0OVF bit) is also set to 1. Clear the
overflow flag to 0 by executing the CLR1 software instruction.

When the TQ0CE bit is set to 1, the 16-bit counter starts incrementing. When it is subsequently detected that a
The pulse width is calculated as follows.
If a valid edge has not been input to the TIQ0m pin by the time the 16-bit counter has incremented up to FFFFH, an
If the overflow flag is set to 1, the pulse width can be calculated as follows.
Remark
Pulse width = Captured value × Count clock cycle
Pulse width = (10000H × Number of times the TQ0OVF bit was set (1) + Captured value) × Count clock cycle
