Function for Synchronization with ADC (PWM to ADC)
This mode performs output of the PWM using the valid signal for the ADC output (synchronization signal)
from the ADC (LPADC/HPADC) as a reference. The following is an overview.

Figure SCU (Sensor Control Unit)-84 PWM Output Mode using ADC Timing as a Reference
When setting the PWM channel n (n = 0, ..., 7), set the following registers in addition to the basic operation
settings.
PWMn_EN register
PWM_SELLn field[2:0] … selects the ADC channel used as the reference
PWM_SELLn field[5:3]
・・・
fixed to “0”
PWM_PASEn register
PWM_DELAYn field … selects the number of clocks for phase adjustment
