HDOUT
The output timing and width of HDOUT (pin 30) can be set in the I
The HD signal input from the HDIN (pin 24) can pass through unaltered and be output from HDOUT.
In this case, the HDOUT output is delayed by 15 clocks from the HDIN input.
Through Mode can be set using the HDSELB bit in the I
The VD signal output from the VDIN (pin 24) can pass through unaltered and be output from VDOUT
There are two output timings: output delayed by 15 clocks from VDIN or output at the same timing as
Timing: HDSTA10~HDSTA5 in Sub-Address 05H and HDSTA4~HDSTA0 in Sub-Address 06H
Output width: HDPW10~HDPW8 in Sub-Address 06H and HDPW7~HDPW0 in Sub-Address 07H

When VDSEL = 0, VDSOFF = 0 and VRNMOD = 0, VD input from VDIN is
output, delayed by 15 clocks.
With all other settings, VDOUT changes with the same timing as HDOUT.
