START_HS[9:0] Start HS Signal , CP Map, Address 0x7C, [3:2] and Address 0x7E, [7:0]
This word operates in a twos compliment mode. Shifting the leading edge of the HSync towards
active video is achieved by selecting from the range 0x000 to 0x1FF. Shifting the leading edge of
the HSync away from active video is achieved by selecting from the range 0x200 to 0x3FF. One
LSB increment is equivalent to
Examples of how to control the BEGIN of the HS timing signal:

This 10-bit word operates in a twos compliment mode. Shifting the trailing edge of the HSync
towards active video is achieved by selecting from the range 0x000 to 0x1FF. Shifting the trailing
edge of the HSync away from active video is achieved by selecting from the range 0x200 to 0x3FF.
One LSB increment is equivalent to
