register) occurs in the 6-phase PWM output mode, the value of the TQnCCR0 register plus 1 is
loaded to the 16-bit counter. In this way, the expected wave can be output even if the cycle value
is changed at the transfer timing of the crest (match between the 16-bit counter value and the
TQnCCR0 register value) timing.
