[6] PWM another setting (if you want)
The settings for the PWM you want to synchronize can be selected as follows:

3.9.11.5.1 PWM Output Phase Calculation Formula
When prescaler is set to 1/1
Phase difference (number of SCU_CLOCK) = PWM_DELAYn + 1
When prescaler is set to 1/2 or higher
Phase difference (number of SCU_CLOCK) = PWM_DELAYn x (2^PWM_CNTENn) - α
Range which α may take
The maximum shift width of the Phase difference shift α is determined by the prescaler setting.
α minimum value = 0
α maximum value = (2^PWM_CNTENn) - 1
For the prescaler 1/2 setting, this is 1[clk]. For the prescaler 1/4 setting, it is 3[clk], and then, at the 1/256
setting, it is 255[clk].
Note: This shift occurs randomly and cannot be controlled.
