NOTE: The signal from CE/MODE Control Logic to PWM/PFM Selector is being fixed to "L" level inside,

and XC9235 series chooses only PWM control.

The signal from CE/MODE Control Logic to PWM/PFM Selector is being fixed to "H" level inside,

and XC9236 series chooses only PWM/PFM automatic switching control.
