Description

This register allows controlling D3 domain power.Following reset VOSRDY will be read 1 by software

Fields

VOSRDY

VOS Ready bit for VCORE voltage scaling output selection. This bit is set to 1 by hardware when Bypass mode is selected in PWR control register 3 (PWR_CR3).
VOS

Voltage scaling selection according to performance These bits control the VCORE voltage level and allow to obtains the best trade-off between power consumption and performance: When increasing the performance, the voltage scaling shall be changed before increasing the system frequency. When decreasing performance, the system frequency shall first be decreased before changing the voltage scaling.
