The det_clken pin is an active-High, synchronous clock-enable pertaining
to the Video Timing Controller (input) interface. This clock enable allows
halting the detector independently from the generator. The internal detector clock
enable is a logical "AND" between the clken and
det_clken inputs. The internal logic that controls the detector
sub-core clock enable is shown in the figure.
