Horizontal timing

The horizontal timing is common for all modes. The
XCL-U100 is provided with a horizontal partial scan
function (HPARTIAL) that is capable of changing the
length of the Hi section of the LVAL signal. Configuring
a minimum of 128 columns anywhere between columns
0 and 1599 of the horizontal effective video area enables
a reduction in the number of columns imported on the
host device (computer) side. The frame rate does not
change even if HPARTIAL is set to ON.
Horizontal timing: Common for each mode
