Description
CSYNC Mode
For details of CSYNC waveform, refer to section
19.5.2, CSYNC.
00: The relation among VSYNC, HSYNC, and
01: Setting prohibited
10: For the interval of three raster scans after
11: 1/2 raster scan after the VSYNC falling
Reserved
These bits are always read as 0. The write value
should always be 0.
CSYNC is as follows.
the falling edge of VSYNC an equivalent
pulse is output, followed by separation pulse
for three raster scans, then an equivalent
pulse for three raster scans, and for the
interval after this the HSYNC waveform is
output as CSYNC.
edge, an equivalent pulse is output for 2.5
raster scans, then separation pulse for 2.5
raster scans, then an equivalent pulse for
2.5 raster scans, and for the interval after
this the HSYNC waveform is output as
CSYNC.
