V_Sync - set this bit HIGH to invert the polarity of the V
Sync timing output signal.
By default, the V Sync signal is active LOW.

H_Blanking - set this bit HIGH to invert the polarity of
the H Blanking timing output signal.
By default, the H Blanking signal will be LOW for the
portion of the video line containing valid video samples.

The value programmed in this register indicates the
pixel start point for the leading edge of the
user-programmed H Sync signal USER1_H.
NOTE: The value programmed in this register must be
less than the value programmed in H_Stop_1.

15-0
The value programmed in this register indicates the
pixel end point for the trailing edge of the
user-programmed H Sync signal USER1_H.
NOTE: The value programmed in this register must not
exceed the maximum number of clock periods per line
of the outgoing standard.

14-0
The value programmed in this register indicates the start
line number of the leading edge of the
user-programmed V Sync signal USER1_V. For
interlaced output standards, this value corresponds to
the odd field number.
NOTE: The value programmed in this register must be
less than the value programmed in V_Stop_1.

14-0
The value programmed in this register indicates the end
line number of the trailing edge of the user-programmed
V Sync signal USER1_V. For interlaced output
standards, this value corresponds to the odd field
number.
NOTE: The value programmed in this register must not
exceed the maximum number of lines per field of the
outgoing standard.
