Hello,TIer.
For we use DM8168 as our box's cpu.and
1.we capture 4*1080P video via 4 channel 4:2:2 video with discrete sync signal.
2.we use Vout0 to output digital video to sii9022a video encoder.
We sendout VGA through DM8168's VGA port.And we use AT9/AL9 as vga's hsync and vsync source.In DM8168's doc,it says that register 0x48140724(SPACE_CTRL0) could be programmed to select vga's sync source.
bit 1 select vga or vout[1]
bit 2 select vga or vout[0]
for that AT9 belongs to vout1,and AL9 belongs to vout0.Could we set register 0x48140724 to 0x06 to make Both AT9/AL9 output vga's hsync and vsync signal?
Is It OK?
