Description
The value programmed in this register indicates the
pixel start point for the leading edge of the
user-programmed H Sync signal USER4_H.
NOTE: The value programmed in this register must be
less than the value programmed in H_Stop_4.
Reference:
The value programmed in this register indicates the
pixel end point for the trailing edge of the
user-programmed H Sync signal USER4_H.
NOTE: The value programmed in this register must not
exceed the maximum number of clock periods per line
of the outgoing standard.
Reference:
Reserved. Set this bit to zero when writing to 68h.
The value programmed in this register indicates the start
line number of the leading edge of the
user-programmed V Sync signal USER4_V. For
interlaced output standards, this value corresponds to
the odd field line number.
NOTE: The value programmed in this register must be
less than the value programmed in V_Stop_4.
Reference:
Reserved. Set this bit to zero when writing to 69h.
The value programmed in this register indicates the end
line number of the trailing edge of the user-programmed
V Sync signal USER4_V. For interlaced output
standards, this value corresponds to the odd field line
number.
NOTE: The value programmed in this register must not
exceed the maximum number of lines per field of the
outgoing standard.
