<1> Matching of the count value of the 16-bit counter and the value of the TQnCCRm register as a result of
<2> Even if the PWM output does not change, the interrupt generated upon a match between the 16-bit
<3> The next match between the 16-bit counter and TQnCCRm register is valid after the counter has changed
If the TQnCCRm register is rewritten after its value matches the value of the 16-bit counter, the next match is
ignored after the first match occurs and the rewritten value is not reflected to the TOQnTm pin output. If the
register is rewritten while the counter is counting down, the match that occurs after the counter starts counting
down is valid (the match that occurs after the counter has started counting up is valid if the register is rewritten
while the counter is counting up).

its counting direction to up or down, and the PWM output changes.
The interrupt culling counter is cleared when the TQnOPT1 register is written. When the interrupt culling
counter has been cleared, the measured number of times the interrupt has occurred is discarded.
Consequently, the interrupt generation interval is temporarily extended.
To avoid this operation, rewrite the TQnOPT1 register in the intermittent batch rewriting mode (transfer
culling mode).
For details of rewriting the TQnOPT1 register, see 10.4.3 Interrupt culling function.
