DESCRIPTION
These bits report a 12-bit value containing the width of one frame
(= 2 fields for interlaced, = 1 field for progressive) of video.
VSYNC period for measured channel =
256*VSYNC Period MSB + VSYNC Period LSB
Units are either number of HSYNC periods or number of
fCRYSTAL/512 periods, depending on setting of VSYNC Units
register.
This register reports a 7-bit value containing the width the
VSYNC pulse. The value returned is for true VSYNC only: it
does not include serrations, EQ pulses, Macrovision pulses,
etc. Units are either number of HSYNC periods or number of
fCRYSTAL/512 periods, depending on setting of VSYNC Units
register.
10-bit value containing the number of pixel clocks between the
trailing edge of HS_OUT and the first valid pixel. SXGA default
values.
12-bit value containing the number of visible image pixels.
SXGA default values.
10-bit value containing the number of lines between the trailing
edge of VSYNC_OUT and the first valid line. SXGA default
values.
12-bit value containing the number of visible lines.
SXGA default values.
0: VSYNC measurement reported in units of lines
(HSYNC periods)
1: VSYNC measurement reported in units of 512 crystal clock
periods
0: New method (Integer count of HS_OUTs)
1: Old method (Time measurement with rounding errors)
