PWM0

When VSEL = Low, it is used to control PWM operation mode of step-down converter

0 : step-down converter would automatically switch the operation mode among CCM

(forced PWM), DCM, and PSM.

1 : step-down converter works only at the forced PWM.

PWM1

When VSEL = High, it is used to control PWM operation mode of step-down converter

0 : step-down converter would automatically switch the operation mode among CCM

(forced PWM), DCM, and PSM.

1 : step-down converter works only at the forced PWM.
