1. In this area, operation is guaranteed at the quartz crystal frequency.
2. When the OSG is disabled, operation in this area is guaranteed at the crystal frequency. When the
OSG is enabled, operation in this area is guaranteed at a frequency of at least f
3. When the OSG is disabled, operation in this area is guaranteed at the quartz crystal frequency. When
the OSG is enabled, access to this area is prevented. The internal frequency is kept at f
