Description

PWR control status register 4

Fields

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 must be changed before increasing the system frequency. When decreasing performance, the system frequency must first be decreased before changing the voltage scaling. Note: Refer to Section Electrical characteristics of the product datasheet for more details.

0 (B_0x0): VOS Low level (default)

1 (B_0x1): VOS High level
VOSRDY

VOS Ready bit

0 (B_0x0): Not ready, voltage level below VOS selected level.

1 (B_0x1): Ready, voltage level at or above VOS selected level.
