Description
Horizontal Sync Signal Width
Set the width of the horizontal sync signals (CL1 and
Hsync) (unit: character = 8 dots).
Specify to the value of (the number of horizontal sync
signal width) -1.
Example: For a horizontal sync signal width of 8 dots.
Reserved
These bits are always read as 0. The write value
should always be 0.
Horizontal Sync Signal Output Position
Set the output position of the horizontal sync signals
(unit: character = 8 dots).
Specify to the value of (the number of horizontal sync
signal output position) -1.
Example: For a LCD module with a width of 640 pixels.
HSYNW = (8 dots/8 dots/character) -1 = 0 =
H'0
HSYNP = [(640/8) +1] -1 = 80 = H'50
In this case, the horizontal sync signal is
active from the 648th through the 655th dot.
