Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Divider Field Override
If Deep-Sleep mode is enabled when the PLL is running, the PLL is
disabled. This 6-bit field contains a system divider field that overrides
the SYSDIV field in the RCC register or the SYSDIV2 field in the RCC2
register during Deep Sleep. This divider is applied to the source selected
by the DSOSCSRC field.
