See Section 3. on page 110 for detailed register description.
DHS is used as an interface from H input pin to software interrupt routines.
DVS is used as an interface from V input pin to software interrupt routines.
These interrupt routines can be used for detection of the frequency of an external sync source. It is set by the HW and must be reset by the
SW. The clamp phase area has higher priority than the screen background area or the character display area and can be shifted independent
from any other register.
