NOTE:
* Input signals with approximately the same frequencies may be regarded as the same
signal.
* The following horizontal timing conditions are recommended (at sync. H, V separate or
H/V composite).
for 31 kHz - 55 kHz horizontal frequency:
Horizontal front porch should be more than 0.1 µs.
Horizontal sync. width should be within 1.0 - 3.8 µs.
Horizontal back porch should be more than 1.2 µs.
Horizontal blanking width should be more than 3.5 µs.
for 55 kHz – 121 kHz horizontal frequency:
Horizontal front porch should be more than 0.1 µs.
Horizontal sync. width should be within 1.0 - 3.0 µs.
Horizontal back porch should be more than 1.1 µs.
Horizontal blanking width should be more than 2.4 µs.
* The following vertical timing conditions are recommended.
Vertical front porch should be more than 10 µs.
Vertical sync. width should be less than 200 µs.
Vertical back porch should be more than 400 µs.
Vertical blanking width should be more than 450 µs.
* In case the front or back porch is extremely long, or the data display time is extremely
short, it may not be able to set the expected size and position.
