α maximum value = (2^PWM_CNTENn) - 1
(1/2 --> 1[clk], 1/4 --> 3[clk], ..., 1/256 --> 255[clk])
Note: This shift occurs randomly and cannot be controlled.
3.9.11.3.2 ADC-PWM Synchronization Settings Procedure (when you do not want to
suspend ADC)
[1]ADC Sampling Start
ADC_EN ON
[2]PWM Start Settings (for 2nd time on) PWM0_PARAM = 0x00070007
PWM_PASE0 = 0x00000001
PWM0_EN = 0x0000000x
PWM0_UPDATE = 0x00000001
[3]PWM suspend settings
PWM0_EN = 0x00000000
PWM0_UPDATE = 0x00000001
[4]ADC Sampling Start (same as [2])
ADC_EN ON
[5]PWM Start Settings (from 2nd time on)
PWM_PASE0 = 0x0000ffff
PWM0_PARAM = 0x00070007
PWM0_EN = 0x0000000x (Selection of ADC synchronization source | 0x1[EN])
PWM0_UPDATE = 0x00000001
PWM_PASE0 = 0x00000001
3.9.11.4 Function for Synchronization with ADC (ADC to PWM)
Using the rising edge of the PWM output as a reference timing, this mode controls the timing that the ADC data
is captured within the SCU.
(must be 1 or larger)
