Horizontal timing
The horizontal timing is common for all modes. The
XCL-5005CR/5005 are provided with a horizontal
partial scan function (HPARTIAL) that is capable of
changing the length of the Hi section of the LVAL signal.
Configuring the setting in increments of 4 columns from
128 columns to 2448 columns without changing the
center position of the effective video area of the
horizontal enables a reduction in the number of columns
imported on the host device (computer) side. The frame
rate does change even if HPARTIAL is set to ON.

When HPARTIAL is set to ON, set the column number
for the effective video area.
Set the read column number to a multiple of 4 between
the range of 128 to 2448. An error will occur if the
configured column number is out of range or not a
multiple of 4.
