VB_CORE

_GO

0: Hold VBUCKCORE at current setting.

1: Ramp BUCKCORE to configured voltage.

While the voltage is ramping, write access is

blocked to BUCKPRO register.

VBUCKCORE_GO is cleared when the

target voltage is reached. While ramping, the

buck is forced into PWM

VB_PRO_

0: Hold VBUCKPRO at current setting.

1: Ramp BUCKPRO to configured voltage.

While the voltage is ramping, write access is

blocked to BUCKPRO register.

VBUCKPRO_GO is cleared when the target

voltage is reached. While ramping, the buck

is forced into PWM

R/W

VB_MEM_

0: Hold VBUCKMEM at current setting

1: Ramp BUCKMEM to configured voltage.

While the voltage is ramping, write access is

blocked to BUCKMEM register.

VBUCKMEM_GO is cleared when the target

voltage is reached. While ramping, the buck

is forced into PWM.
