Stop - Read/Write
The STOP value is the value of the Horizontal down
counter at which the HCLKEN signal becomes inactive
(stops). This indicates the end of the video clock for the
Horizontal frame. Please refer to video signalling timing
diagrams in
internal clock signal. The SPCLK output is enabled by the
logical AND of VCLKEN and HCLKEN.
